"We continue to discover how myriad complex interactions between Earth's solid interior and the exterior world of water, air, and ice that we inhabit sustain and impact life."
Lamont's exploration of the largely unknown terrain beneath the world's oceans began at the inception of the observatory more than 70 years ago. Today, members of the Marine & Polar Geophysics (MPG) Division remain explorers at heart, motivated by the drive to understand some of the most remote and dangerous reaches of our planet, from the deepest oceans to the polar ice sheets.
Today’s tools of exploration have evolved from simple echosounders and towed seismic source-and-receiver instruments, to MultiChannel Seismic (MCS) Reflection techniques that allow researchers to probe more deeply into the Earth. Multibeam bathymetric and side-looking sonar imagers can map large areas of the seafloor in ever greater detail. While the surface ship has remained the "workhorse" of MPG research, other types of platforms and vehicles are playing an increasingly important role. These include satellites, with their ability to cover large areas of the oceans very rapidly (and revisit the same area many times), and innovative remote sensing equipment, as well as data systems for mapping and visualizations.
The IcePod, designed and developed at Lamont, offers an airborne integrated ice imaging system that can measure in detail both the ice surface and the ice bed. The Marine Geoscience Data System (MGDS) provides a suite of tools and services for accessing marine geoscience research data acquired throughout the global oceans and adjoining continental margins.
Making new and exciting observations of the ice sheets and geological processes occurring on and beneath the seafloor is a key element of MPG Division research.
Lamont points to a legacy of discoveries, including seafloor spreading, which led to the general acceptance of plate tectonics as the broad foundation for understanding how our planet works. Communities of scientists emerged to test hypotheses generated by the plate tectonics paradigm in the oceans.
Lamont scientists have used ocean drilling data and technology to study the sediments and hard rocks beneath the seafloor, as well as the fluids that flow through them. One of Lamont's major contributions to scientific ocean drilling was the establishment of the Borehole Research Group to provide down-hole geophysical measurement services to the Ocean Drilling Program (now the International Ocean Discovery Program), developing new types of borehole logging instruments, adapting oil-field logging tools for use in ocean research drilling, and maintaining a database of all logging measurements on behalf of the ocean drilling community.

I am currently a Lamont Associate Research Professor at the Lamont-Doherty Earth Observatory of Columbia University. I research the general circulation of the atmosphere, including the midlatitude jet streams, storm tracks and monsoon circulation, using observations and numerical model simulations. My recent research projects focus on understanding the impact of Arctic sea ice loss on the midlatitude weather and climate as well as understanding the summer monsoon circulation and its associated troposphere-stratosphere transport. Before joining Lamont, I worked an Assistant Professor in the Department of Earth, Atmospheric, and Planetary Sciences at Purdue University and before that, a postdoctoral research associate at the Courant Institute of Mathematical Sciences. I received Ph.D. in Applied Mathematics from Columbia University in 2011.
Dr. Yushu Xia's research is centered around soil health and natural climate solutions. Her overall research goal is to promote environmental sustainability, enhance ecosystem productivity and biodiversity, and mitigate climate change by improving soil health while reducing greenhouse gas emissions.
Her research leverages multi-scale datasets (e.g., field, lab, survey/literature, remote sensing) and modeling tools (both empirical and process-based) to improve the quantification of ecosystem services and ecosystem service outcomes, such as carbon sequestration, greenhouse gas emissions, water dynamics, and ecosystem productivity. Her previous work mainly focused on cropland and grassland ecosystems.
Dr. Yongming Han is currently a full professor of the Institute of Earth Environment, Chinese Academy of Sciences. His research interests are related to geochemistry, particulate matter pollution, environmental and climate change, the linkage between the very short atmospheric time series and longer sedimentary records of various pollutants, especially black carbon and combustion products. He is particularly interested in black carbon in different compartments (atmosphere, soils and sediments), including its methodology, origins, transport, deposition, and fate. He seeks to reconstruct past wildfire history and understands the inherent mechanisms regarding biomass burning emissions and climate change. Recently, his research focuses on the interaction between human activities and natural forcing during the Anthropocene period. Dr. Han's research has been funded by National Natural Science Foundation of China, Chinese Academy of Science, and Ministry of Science and Technology of the People´s Republic of China etc.
I am a Research Professor at the Lamont-Doherty Earth Observatory, The Earth Institute, Columbia University. My research is concerned with characterizing and understanding climate variability and change using observations and global climate models. I am particularly interested in the role of the oceans in climate variability on time scales of years to decades. Throughout my career at Lamont I have mentored graduate and undergraduate students in their research. With my collaborators and students, I published extensively on the topics modern and paleo climate variability. I co-edited and contributed to the 2003 American Geophysical Union Monograph: The North Atlantic Oscillation: significance and environmental impact and was one of the authors of the 1995 National Academies report on Climate Variability on Decade-to-Century Time Scales. Between 2003 and 2014 I served as the director of the Cooperative Institute for Climate Applications and Research (CICAR), a research partnership between the National Oceanic and Atmospheric Administration (NOAA) and Columbia University. I co-chaired the CLIVAR working group on Decadal Climate Variability and Predictability, which has been sunset last year. I currently co-chair the World Climate Research Program (WCRP) the panel on Grand Challenge on Near Term Climate Prediction. In 2013 I was elected Fellow of the American Meteorological Society.
I am a postdoctoral research scientist at Columbia University, Lamont-Doherty Earth Observatory. I’m now working on the effects of regional emissions of anthropogenic aerosols on climate change.
I got my Bachelor's degree in Atmospheric Sciences from the Ocean University of China in June 2012. Later, I pursued my Master's degree from the Chinese Academy of Meteorological Sciences, which I completed in June 2015. I earned my Ph.D. degree from the State University of New York at Albany in July 2021. From 2021 to 2023, I worked as a Postdoctoral Research Scientist in the Atmospheric and Oceanic Sciences (AOS) program at Princeton University.
I have engaged in studies of variability of the Antarctic atmosphere-ocean-sea ice system and its role in global climate since 1995. My research has progressed from the identification of polar-global linkages, expanded to an ENSO-Antarctic Dipole teleconnection mechanism study, and finally resulted in an Antarctic sea ice forecast. At the same time, I have utilized space-born scatterometer observations and developed a series of studies focused on air-sea interactions on synoptic time scales, ranging from cyclone-sea ice interaction, high wind evaluations to satellite enhanced cyclone statistics in the Southern Ocean. With the accumulation of knowledge regarding climate variability in the atmosphere, sea ice and at the air-sea interface, an understanding of the ocean’s role in the mid-high latitudes climate system becomes increasingly important. However, this task is much more challenging because of sparse observations in the Southern Ocean. In recent years, I have developed a few oceanic field programs to advance our knowledge of how the polar ocean plays out in the climate system. I also developed statistical forecast models for polar sea ice fields and maintain Antarctic and Arctic sea ice seasonal predictions routinely.
My research is geared toward understanding global climate change, including current anthropogenic driven changes and past changes to the Earth System. I investigate the natural modes and underlying forcing mechanisms of past climate variability, with the goal of developing a better understanding of how the Earth System responds to natural and human-induced perturbations.
I’m interested in the ways that environmental and climatic information becomes incorporated into the lipids of living organisms and preserved in the geological record, and I take advantage of these mechanisms to examine past environmental change. Lake sediments are comprehensive archives of changes that have taken place through time, and they allow valuable and quantitative reconstructions of past environmental parameters. I use organic compounds and the stable isotope ratios of hydrogen, carbon, and nitrogen found in them, to reconstruct past climates and environments.

William is a National Science Foundation Postdoctoral Fellow at Lamont-Doherty Earth Observatory of Columbia University. William's research involves using seismic data to image the interior of the Earth, and integrate geodynamic models with the inferred seismic structure to better understand the long-term evolution of our planet. Although the evolution of oceanic plates plays a crucial role in plate tectonics, and therefore Earth evolution, the structure beneath ocean basins remains largely unexplored. He uses ocean bottom seismometers to address a range of problems in marine geophysics, including deep processes related mid-ocean ridges, structural and mechanical properties of the lithosphere and asthenosphere, and the structure and evolution of subduction zones.
William began at Lamont-Doherty Earth Observatory in the fall of 2019. He completed his PhD at the University of California, Berkeley in 2019, and his B.A. in physics and astrophysics from Harvard University in 2012

- My research aim is to extract as much quantifiable information as possible from seismic data anywhere within reach of human interaction, from the ocean interior to our deepest drilling projects (and eventually beyond). Primarily, I use and develop attribute analyses to (1) determine viability of basaltic basins for CO2 sequestration, (2) characterize sediment properties on continental margins to assess natural hazards risk, and (3) map turbulent behavior of dynamic mesoscale ocean features. (1) CO2 storage in basaltic basins: I have been examining the CO2 storage potential of Mesozoic rift basins offshore the US east coast on the Long Island Platform. Detailed prestack waveform inversion sheds insight into basin compositions, and thus the character of the rock infill and volumetric storage potential. (2) Seabed stability and slope failure: I am working with collaborators to investigate fluid overpressure off the U.S. east coast and its role in large submarine landslides. Such slides occur frequently, covering ~20% of the seafloor, and are capable of producing tsunamis along the heavily populated coast. Using advanced computational techniques like prestack waveform inversion and machine learning, we gain quantitative insight into seabed conditions and work toward a comprehensive understanding of risk associated with regional submarine landslides. (3) Seismic oceanography: My research goal is to explore energetics in the oceanic interior by mapping diapycnal diffusivity of meso- and sub-mesoscale ocean structures in conjunction with temperature and salinity profiles inverted from seismic data. I am particularly interested in regions with high internal wave activity, seamounts, and large eddies.
I’m an agro-climatologist studying the dynamics of climate variability and its relation to food security using reanalysis products, remote sensing observations and model simulations.

I am a marine geophysicist interested in the interplay between relatively large-scale geophysical processes and the microbial biosphere. I am currently studying the tidal modulation of aqueous fluid flow within mid-ocean ridge hydrothermal systems, with the hope of understanding how such flow variations can affect subseafloor primary production. I also study spatial variations in the tidal triggering of microearthquakes within ridge systems, and I study problems in acoustics associated with high-temperature hydrothermal vents and seafloor seismic networks. Ultimately my work has implications for theories about the origins and evolution of life on this planet, and for theories regarding life elsewhere in the universe. I use numerical models to investigate these processes, and I develop new observational techniques and seafloor instrumentation to verify model predictions.
Gentleman Adventurer, 1969-present.
I'm a Ph.D. candidate at Columbia University in the Department of Earth and Environmental Sciences working with Richard Seager. My research focuses on better understanding hydroclimate variability and change in the western U.S. and similar regions around the world under climate change. Currently, I'm studying the effect of climate on wildfires in the West. I graduated from Princeton University in 2019 with an A.B. in Physics and a certificate in Environmental Studies. My undergraduate work explored the impacts of hemispherically asymmetric volcanic eruptions on Sahel hydroclimate. I continued this research in Gabe Vecchi's group after graduating while also working as an Outward Bound instructor for middle- and high-school students in New York City public schools.
My research is focused on magmas associated with the plate tectonic cycle, at both divergent and convergent plate margins. My main contributions have been to the understanding of:
* Magma generation: quantifying the roles of decompression, temperature and water in driving mantle melting
* Crustal recycling at subduction zones: providing global flux estimates of marine sediment subducted into oceanic trenches, and tracing sediment geochemically from the seafloor to arc volcanoes
* Water content of magmas, and the effects on magma evolution, mantle and slab temperature, and eruptive vigor.
My tools are geochemical, field work has taken me to Nicaragua and the Aleutians, and to sea. I have served on the MARGINS steering committee, the editorial boards of Geology and Earth & Planetary Science Letters, the EarthScope Advisory Committee, as co-chief scientist on Leg 185 of the Ocean Drilling Program, co-lead-author of the SZ4D Vision Document, and one of the writing team for the NAS ERUPT Report.

Steven Chillrud, Ph.D. is a Lamont Research Professor at Lamont-Doherty Earth Observatory of Columbia University. He describes himself as an environmental geochemist interested in public health research. Much of his research is focused on the role of particles in the transport, behavior, and fate of chemical contaminants. His expertise in exposure assessment includes the development and testing of air samplers and analytical methods for quantifying airborne contaminants.
Dr. Chillrud’s formal training was in geochemistry and focused on analytical chemistry and understanding transport and fate of particle-associated contaminants in the Hudson River Watershed through the use of dated sediment cores. During his post-doc at Columbia University, he began reconstructing the history of atmospheric deposition of a wide array of particle-bound contaminants into NYC throughout the late 19th and 20th centuries.
Dr. Chillrud’s research spans air, water and soil pollution in both urban and rural settings. He serves as Director of the Exposure Assessment Core Facility of the Center for Environmental Health in Northern Manhattan, which supports a wide array of air and water pollution projects, including supporting projects in low- and middle-income countries and overseeing the development and use of air sampling equipment.
Dr. Chillrud’s early work identified short commutes in the subway system as being the dominant exposure pathway for NYC adolescents to airborne iron, manganese, and chromium. Frustration with limitations of pumps and monitors led to efforts developing and testing miniaturized, personal air samplers for black carbon and multiple air pollutants.
Dr. Chillrud is also active in research on enhanced remediation methods of groundwater and research translation within Columbia’s Superfund Program on Health Effects and Geochemistry of Arsenic. He is an active member of Columbia’s CleanAir Toolbox, a collaboration of 20 research groups across the Columbia Climate School focused on solutions-oriented work to improve air quality in cities across the Global South, also referred to as low and middle income countries.
Dr. Chillrud teaches classes related to sustainability in SIPA’s Environmental Science and Policy Program and the the SPS Master’s Program in Science of Sustainability.

Routinely used isotopic approaches include Rb-Sr, Sm-Nd, Th-U-Pb, Lu-Hf, radiocarbon, and intermediate products of U-decay. These tools can be applied across the geosciences and across geological time, and Professor Goldstein’s research has addressed a wide range of topics ranging from the early history of the Earth to recent climate change. He has published more than 160 peer-reviewed papers. Professor Goldstein is a recipient of the American Geophysical Union’s Norman L. Bowen Award “in recognition of outstanding contributions to the fields of volcanology, geochemistry, and petrology,” and is a Fellow of the American Geophysical Union and the Geochemical Society/European Association of Geochemistry. He is also a recipient of Columbia’s Lenfest Distinguished Faculty Award. He especially appreciates two awards: the Excellence in Teaching Award from the Graduate Student Committee of the Department of Earth and Environmental Sciences, and the Great Teacher Award from the Society of Columbia Graduates. Prior to coming to Columbia in 1996, Professor Goldstein was Staff Scientist at the Max-Planck-Institut für Chemie in Mainz Germany, in the Geochemistry Division. He received his Ph.D. from Columbia in 1986, his M.A. from Harvard in 1978, and his B.A. from Columbia College in 1976.
I am a geochronologist working on a diverse suite of earth science problems including climate change, critical mineral resources, deep-time thermochronology, winemaking, and earthquakes hazards. My primary toolkit is noble gas geochemistry, but I also dabble in water isotopes, statistics, geospatial modeling, and geologic mapping. I have a hard time turning down interesting new projects, and I shy away from the type of rote measurements that would probably make for a more impressive publication record.
In 1894, Fridjof Nansen, a Norwegian scientist, was surprised to see on an expedition that Arctic sea ice wasn't always white and pristine, but was often discolored by dust and mud. He vowed to return one day to discover where the sediment was coming from. But Nansen never did return, and 100 years later I became intrigued by the same question when I saw the wide expanses of "dirty" ice in the Arctic. As a result, my main research interest is determining the role of sea ice - a transport mechanism unique to the Arctic - in the redistribution of sediments and pollutants in the Arctic. When I sample a floe for sediment or pollutant load, I want to know where it came from, what's happened to it since the ice first formed and where the ice is going to melt and release its incorporated materials.
I am developing and using a variety of methods to find answers to these questions. In a broader view, an unusual combination of environmental conditions in the Arctic exacerbates climate change, ozone depletion and deposition of pollutants. DDT and heavy metals from regions far to the south accumulate in the Arctic marine food chain. I am interested in finding out how warming in the Arctic could affect the pathways and fate of contaminants.
I’m a postdoctoral research scientist in the Polar Geophysics Group working with Jonathan Kingslake, Meredith Nettles and Laura Stevens (Oxford). I study the mechanics of hydrological and glaciological systems, as well as their interplay with the solid Earth, using geophysical techniques like satellite geodesy, field deployments, data analysis, and modeling. I'm particularly interested in understanding the impact of human activity and climate change on societally-critical systems like ice sheets, aquifers, continental water storage, and faults. I'm currently working on understanding the role of surface meltwater and groundwater in ice sheet dynamics.
Spahr Webb holds the Jerome M. Paros/Lamont Research professorship in Observational Sciences at the Lamont Doherty Earth Observatory which Is part of Columbia University’s new Climate School. He is also an Adjunct Professor within the Department of Earth and Environmental Sciences Department of the Columbia University. His group develops instrumentation to better observe geophysical and oceanographic processes. A principle focus now is on subduction zones and the hazards of megathrust earthquakes with an emphasis on observing slow slip events (SSEs or slow earthquakes). The distribution of slip in SSEs should inform on the coupling behavior of megathrust faults and which have preceded several recent giant earthquakes, and thus may provide the potential for early warning. Other efforts include measuring deformation near the trench of subduction zones using GPS-acoustic techniques, monitoring magma chamber processes beneath Axial volcano using the compliance method.
Current projects include a two year project starting Oct. 2022 using absolute pressure gauges combined with oceanographic observations and on shore and offshore geodetic observations to observe slow slip events (earthquakes) offshore of New Zealand.
A group of three GPS-A (GPS acoustic) geodetic sites were established offshore the Aleutian subduction zone in 2018 in the Shumagin seismic gap region about 70km from the trench. The sites were used to measure interseismic strain accumulation and then also the seafloor displacements caused by the huge 2021 Sand Point and Simenof and 2022 Chignik earthquakes that occured beneath the array.
Three instruments were temporarily deployed to measure seafloor compliance to investigate the magma chamber beneath Axial Volcano in June 2022.
Spahr Webb hold B.S. degrees in Physics and also Earth and Planetary Sciences from MIT and a PhD in oceanography from the Scripps Institution of Oceanography.

Robin Bell, AGU president (2019 – 2020), has been a member of AGU for more than 30 years. She is a past president of the Cryosphere section and was elected as an AGU Fellow in 2011. Bell received her undergraduate degree in geology from Middlebury College in Vermont and her Ph.D. in geophysics from Columbia University in 1989. Since completing her doctorate, Bell has led the research at the Lamont-Doherty Earth Observatory on ice sheets, tectonics, rivers, and mid-ocean ridges.
Currently, Bell is a Palisades Geophysical Institute (PGI) Lamont Research Professor, directing research programs in Antarctica and Greenland, and she has developed technology to monitor our changing planet. Bell has coordinated 10 major aero-geophysical expeditions to Antarctica and Greenland, studying what makes ice sheets collapse. She has discovered a volcano beneath the West Antarctic ice sheet, several large lakes locked beneath two miles of ice, and demonstrated that ice sheets could thicken from below. Bell also led a Lamont team to map the Hudson River from Staten Island to Albany.
In 2006, Bell received an honorary degree from Middlebury College and had an Antarctic Mountain named after her. During the International Polar Year, Bell led a major expedition to Antarctica to explore the last unknown mountain range on Earth, the Gamburtsev Mountains, which were completely covered with ice. Bell’s team discovered that water hidden beneath the ice sheet runs uphill. Using the new IcePod and gravity technologies, Bell’s team is currently exploring the Ross Ice Shelf, a floating piece of ice the size of France that covers the least-known piece of Earth’s ocean floor.
What can the past tell us about the future? Much of my work is oriented around understanding what the historical record can tell us about climate change, and especially how changes in the composition of the atmosphere affect the flows of energy within the earth system -- the so-called "radiative forcing." On shorter time scales I work on a range of problems related to clouds, radiation, circulation, and climate. One practical thread is related to the nuts-and-bolts of building models. Radiation is the ultimate driver for every atmospheric motion so every model of the atmosphere needs an accurate representation. I'm especially interested in identifying a range of strategies for balancing accuracy and computational cost based on the scales at which radiation couples to circulation. I have a long-standing interest in interpreting remote-sensing measurements. Still inspired by one of my first mentors, I'm especially interested in what we can learn from different views of the same aspect of the world.

Anderson graduated summa cum laude from the University of Washington in 1975 with a double major in chemistry and in oceanography. In 1981 he was awarded his PhD in Chemical Oceanography from the Massachusetts Institute of Technology - Woods Hole Oceanographic Institution Joint Program in Oceanography. Since 1981 he has been at the Lamont Doherty Earth Observatory, rising through the ranks until reaching his current position of Ewing-Lamont Research Professor in 2010. Along the way he has taught chemistry of the ocean and of continental waters and served as Associate Director for the Observatory (2003 to 2008), when he oversaw the construction of the Comer building for the Geochemistry Division.
As a student, Anderson was convinced that naturally occurring radionuclides could be used to quantify the rates of key processes in marine biogeochemical cycles. Some of the essential principles were defined initially in the paper by Bacon and Anderson (1982). GEOSECS, the first program to systematically study the chemistry of the ocean at a global scale, was then demonstrating the value of synthesizing results from diverse sources. In 2000, following these principles, Anderson teamed with international scientists as architects of a program to study the marine biogeochemistry trace elements and their isotopes, GEOTRACES. The value of using radionuclides to establish rates is shown in Anderson et al. (2009), where rapid changes in the circulation of the ocean around Antarctica were first demonstrated to be responsible for the release of CO2 to the atmosphere as Earth emerged from the last ice age. Work on this project led to a partnership with George Denton to synthesize records from the ocean and from land, respectively, to define features that characterized Earth’s last transition from ice age to interglacial conditions (Denton & Anderson et al., 2010). By elucidating the important role of ocean circulation, it was possible to determine that the low atmospheric CO2 levels of the Pleistocene ice ages was due to increased storage of CO2 in the deep ocean (Anderson et al., 2019). Now, a growing number of synthesis papers from the GEOTRACES program (Anderson, 2020) are exploiting naturally occurring radionuclides to establish rates of processes that regulate the chemistry of the ocean, such as the delivery of dust from the continents, the sinking flux of biogenic material exported from the surface ocean, and the accumulation of sediments world wide, bringing to fruition Anderson’s dream in graduate school.
I am a climate scientist at Lamont Doherty Earth Observatory. I was born in the United Kingdom and did my undergraduate studies at the University of Liverpool where I was introduced to atmospheric sciences, climate studies and oceanography. I moved to New York and Columbia to do my PhD under Mark Cane and Steve Zebiak in tropical atmosphere-ocean and climate dynamics. After a postdoc at the University of Washington I returned to Lamont and have been here ever since. My work concerns climate variability and change on timescales of weeks to millennia with a special focus on atmosphere-ocean interaction, the causes of droughts and hydro climate variability and change. My work uses numerical models, observations and proxy climate reconstructions from paleoclimate records and covers the globe.

Pierre Dutrieux received his Ph.D in Oceanography from the University of Hawaii in 2009. His PhD work investigated tropical ocean circulation and dynamics with a particular focus on meso-scale eddy variability. Since then he directed his attention to the interaction between the oceans and the polar ice sheets, first at the British Antarctic Survey (until 2015), at the Polar Science Center, APL-UW, and now at LDEO.
Using pioneering autonomous platforms (Autosub 3) to roam under at least 300 m thick ice for tens of kilometers, his research demonstrated that warm waters >3° above the in situ freezing point reaches the grounding line (where the ice sheet comes afloat and eventually extends into an ice shelf) of Pine Island Glacier, in West Antarctica. This water efficiently melts the ice shelf, reduces its buttressing effect on the flow of grounded ice into the ocean, and is now shown to be a key driver of a wide-spread glacial acceleration and retreat in the Amundsen Sea, West Antarctica, with important contributions to sea level rise, the freshwater budget of the Southern Ocean and possible impacts on the global thermohaline circulation and local primary production.
Using autonomous platforms, ship-borne ocean observations, ground-based and airborne radar observations, satellite observations and numerical modelling, Pierre further demonstrated that in this setting glacial melt is strongly modulated in time by remote climatic sources, and that the spatial distribution of melt is complex, varying at meters to kilometers scales, and carving and interacting with intriguing landscapes under the ice.
Developing new observational tools and integrating new understanding into predictive models, Pierre continues his work to shed light on the processes controlling the oceanic melting of glacial ice and its implications for the climate system.
Philip C. LaPorta is an Adjunct Senior Research Scientist at Lamont Doherty Earth Observatory and Lifetime Director at The Center for the Investigation of Native and Ancient Quarries (CINAQ). His research has strived to forge a meld between the principles of the geological sciences, and the systematic investigation of prehistoric quarries and ancient mines. This realm of research represents the first logical subdivision of the broader field of Geo-Archaeology.
In 1989, LaPorta published the first manuscript, and associated field excursion guide, focused directly on the stratigraphic relations of prehistoric chert quarries in the northeastern United States (NYSGA, 1989). The Prehistoric Quarries and Early Mines Interest Group (PQEMIG) was founded by LaPorta in 2006 for the Society of American Archaeology. PQEMIG is an outgrowth of LaPorta’s research, and Philip served as its first director from 2005-2010. In 2006, LaPorta led the first Geological Society of America national meeting post-conference field trips to prehistoric quarries and mines in the New York metropolitan area. Dr. LaPorta’s dissertation (2009) includes the first complete stratigraphic section, approx. 3,300’ at a scale of 1:98, for the Cambrian and Ordovician chert–bearing carbonates of the Kittatinny Supergroup in the tristate metropolitan area. Additionally, Philip mapped greater than 2,000 prehistoric quarries and mines within the metropolitan region. The dissertation serves as a type section for Cambrian and Ordovician nodular cherts, as well as a provenance tool for archaeological investigations.
In 2012, Philip founded CINAQ, a 501.c3 non-profit education charter in New York State, with the mission of educating the public and Indigenous peoples on this significant and much maligned resource. Additionally, CINAQ houses the nation’s largest and most complete lithiotech; a taxonomically organized collection of geological materials, obtained from both prehistoric, as well as historic, mines, quarries, and outcrops.
Through the years, Dr. LaPorta’s research has grown to international levels. His expertise has brought him to investigate Lower to Middle Paleolithic quarries in India and Israel; as well as Neolithic, Chalcolithic and Bronze age quarries in Israel, Bulgaria and Poland. Most recently, since 2003, Philip has been researching the Neolithic, Proto-dynastic, as well as Old Kingdom Pharonic quarries of Egypt. Dr. LaPorta is unfolding new researches in geomicrobiology, neotectonics, cosmogenic isotope studies and paleotoxicology.
Philip received his bachelor’s degree from Rutgers University (1977), his masters’ degrees from Queen’s College (1990, 1996), and his doctorate from the CUNY Graduate Center (2009). Along the way, Philip founded LaPorta and Associates, Geological Consultants (1993-2013), now LaPorta Geological Consultants (2013 to present).
Through the years, Dr. LaPorta has designed geology courses for anthropology, archaeology and geography majors and graduated the first transdisciplinary majors from the CUNY system (1990 through 1995), employing his Cambrian-Ordovician geological and archaeological research as both a field and classroom laboratory. Philip’s students went on to earn master’s degrees from Indiana University, Lamont Doherty, University of Kentucky, University of Rhode Island, and Texas A&M University. Several of Dr. LaPorta’s former students earned Ph.D.’s from the University of Michigan, Lamont Doherty, and the University of Kentucky. Philip has taught economic geology and ore deposit studies, optical mineralogy, invertebrate paleontology, geological field methods and mapping, as well as geo-archaeology field school at Queens, Hunter and Lehman colleges in the CUNY System, as well as at Montclair State and Pace universities.

The evolution of continental ecosystems (including their external and internal controls and their biological and physical components) is my overall area of research. I am especially interested in the pattern, causes and effects of climate change on geological time scales, mass extinctions, and the effects of evolutionary innovations on global biogeochemical cycles.
In recent years my students and I have engaged in multidisciplinary projects including: drilling and recovering more than 20,000 feet of core from Triassic lake deposits in New Jersey to understand the influence of variations of the earth's orbit on tropical climate, detailed analysis of the great mass extinction 200 million years ago that set the stage for the dominance of the dinosaurs, excavations at major fossil vertebrate sites throughout eastern North America and Morocco, and the evolutionary processes mediating global carbon cycling.
My approach is to use whatever techniques are available to understand ancient earth's biological and physical systems, and consequently, students involved in these areas have used a broad range of disciplines including structural geology, palynology, geochemistry, geophysics and paleontology.

I am a geophysicist who works mainly on sedimentary systems with projects related both to tectonics and earthquakes, and to sea level and stratigraphy. A particular interest is vertical motions of the Earth’s surface and their preservation in the sedimentary record. My main field area is currently Bangladesh where I work both on the heavily-sedimented IndoBurma subduction zone (IBSZ), including the earthquake hazard, and on deltaic processes in the Ganges-Brahmaputra Delta (GBD), including sea level rise, land subsidence, sedimentation and river avulsions. I have worked in Bangladesh, and adjacent parts of India and Myanmar, for 20 years, taking part in and leading a number of field campaigns. I am also currently working on tectonics in Western Turkey, and on fresh and salty groundwater in both Bangladesh and offshore New Jersey.
My research interests fall under the broad heading of climate dynamics. Currently, I am working to better understand i) the dynamic and thermodynamic controls of the atmospheric water cycle in present-day and future climates, and ii) the atmosphere/ocean effects of annular mode/North Atlantic Oscillation (NAO) variability.

Maureen E. Raymo is Co-Founding Dean Emerita of the Columbia Climate School, past Director of Lamont-Doherty Earth Observatory (July 2020-June 2023), and G. Unger Vetlesen Professor of Earth & Environmental Sciences.
She has degrees from Brown and Columbia Universities and studies the history and causes of climate change in Earth's past. She is best known for the Uplift-Weathering Hypothesis that ties global cooling and the onset of the ice ages to a drawdown in atmospheric CO2 caused by the uplift of the Himalayas and Tibetan Plateau.
In addition to publishing fundamental work on the stratigraphy and chronology of the recent geologic epochs, Raymo has also proposed hypotheses explaining the patterns of ice sheet variability observed over the last few million years and developed new ways of studying past sea level change. In 2014 she was the first woman to be awarded the Wollaston Medal by the Geological Society of London, their most prestigious award given out annually since 1831.
Raymo’s research has always focused on documenting how and discovering why the Earth's oceans, biogeochemical cycles, and climate have changed in the past, knowledge that is integrated with numerical models of past and future climate. Through detailed analysis of deep sea sediment cores, she has generated records of geochemical, paleontological, and paleoclimatic change that have advanced the study of Earth’s climate on tectonic, orbital, and millennial time scales.
For much of her career she has also worked to improve the timescales and stratigraphy that provide the foundation for the study of Earth’s history. Most recently her research group has focused on the reconstruction of sea level and ice volume during past warm climate intervals with the goal of improving predictions of future sea level rise in response to global warming.
Martin Stute, Alena Wels Hirschorn'58 and Martin Hirschorn Professor in Environmental and Applied Sciences began teaching at Barnard in 1993 and became a full-time faculty member in 1995. He serves as Co-Chair (or Chair) of Barnard's Department of Environmental Science.
Professor Stute holds a concurrent position as Adjunct Senior Research Scientist at the Lamont-Doherty Earth Observatory and is a member of the faculty of Columbia's Department of Earth and Environmental Science. Professor Stute teaches such courses as Environmental Data Analysis, Hydrology, Workshop in Sustainable Development and leads the joint Columbia/Barnard Senior Research Seminar, the capstone experience for our majors.
His research interests include water resources, contaminant transport in groundwater, Carbon sequestration, unconventional gas production, paleoclimate, mathematical modeling of environmental phenomena, and the social and economic impact of global environmental change.
Regarding his development as an environmental scientist, Professor Stute says, "I knew early on that I wanted to dedicate my career to environmental issues and studied physics, because there was no such thing as environmental science to study at a university back then. My PhD thesis research topic at the University of Heidelberg focused on novel tracer techniques to study the dynamics of ground water flow, and the use of ground water as an archive of paleoclimate. I have been interested in water issues ever since and can still hardly resist to take a plunge into a thermal spring I encounter or take a sip from a well that might tap an interesting aquifer. I believe that water will play an increasingly important role in our attempts to achieve a sustainable global development."
Like so many other oceanographers, I was born in Brooklyn, New York, in the days before the Dodgers left and precipitated the decline of American civilization. I was lucky enough to work on the tropical oceans in the era when we came to understand and predict El Niño and the Southern Oscillation (ENSO), the now famous pattern of interannual climate variability with well-publicized global consequences. Together with then student Steve Zebiak, I devised the first numerical model able to simulate ENSO, and in 1985 we used this model to make the first physically based forecasts of El Niño. Over the years the Zebiak-Cane model has been the primary tool used by many investigators to enhance understanding of ENSO. Making predictions led to asking what to do with them. So I began to work on the impact of El Niño and other climate variability on human activity, especially agriculture and health. My 1994 paper (with student Gidon Eshel) on the strong effect of El Niño on the maize crop in Zimbabwe has been influential in prompting decision makers to consider climate variability. This line of inquiry led to the creation of the International Research Institute for Climate and Society, housed here at Lamont. I also founded and directed the Masters Program in Climate and Society. While I continue to work on equatorial dynamics, El Niño, prediction of climate variations and climate impacts, and global climate issues, current work is dominated by concern for the impacts of human influence on the climate system. IN addition to the futurre and the present , my interest is drawn to explaining the variations in the paleoclimate record, especially the astoundingly strong abrupt changes and the succession of droughts over the past millennium.

Lynn Sykes has been involved for 55 years in the verification of underground nuclear testing and the long battle to obtain a total ban on nuclear testing. In 1986 the Federation of American Scientists presented him and two colleagues with its Public Service Award for working to revive scientific and public interest in a comprehensive nuclear test ban treaty. He along with Walter Pitman from the Lamont-Doherty Earth Observatory of Columbia University and Jason Morgan of Princeton showed unequivocally that the earth’s outermost layers consist of nearly rigid plates that move over the surface of the earth. That major revolution is called plate tectonics.
Sykes, a long time resident of Palisades New York became a member of the Lamont Staff in 1965 after graduating from M.I. T. followed by a PhD at Columbia. He has authored more than 135 scientific articles, including 35 on the nuclear testing. He was a member of the U.S. delegation that traveled to the Soviet Union in 1974 to negotiate the Threshold Test Ban Treaty. He testified before the U.S. Congress numerous times as an expert on nuclear-test verification, a subject with large scientific and public policy components.
Plate tectonics revolutionized the study of the earth’s crust, providing a understanding of the formation of mountain ranges, the drifting of the continents, volcanoes, earthquakes, ocean basins, mid-oceanic ridges, deep sea trenches, the evolution of climate and the distribution of natural resources. Sykes proved the importance of great faults that intersect mid-ocean ridges in accommodating plate motion. Dr. Marcia McNutt a geophysicist and President of the U.S. National Academy of Sciences called the discovery of plate tectonics “one of the top ten scientific accomplishments of the second half of the 20th Century.”
Sykes is a member of the National Academy of Sciences, the American Academy of Arts and Sciences, a Fellow of the Geological Society of America and of the American Geophysical Union, which honored him with its Macelwane and Bucher awards. He also received the Seismological Society of America’s most prestigious H.F. Reid medal. He received an honorary degree from Columbia University in 2018. While officially retired, he continues his research on earthquakes and explosions. He was born in Pittsburgh Pennsylvania in 1937 and grew up near Washington DC.

I have several research interests in the intersection between geology, climate change and energy. I am especially interested in geologic carbon sequestration and how fluid-gas-rock reactions can lead to secure and permanent sequestration of industrial carbon dioxide., Currently, I am working in three overlapping areas:
- CO2-water-rock interactions and reactive flow in deep aquifers
- Fluid flow and solute transport in saturated media
- Subsurface fluid injection and geomechanical stability of reservoir rocks
Some of my projects include:
- Secure and long-term sequestration of industrial carbon dioxide in calcium-magnesium silicate rocks
- Big Sky Carbon Sequestration Partnership
- Mineral carbon dioxide sequestration into basalt - CarbFix Project, Iceland
- Natural carbon sequestration in ophiolite peridotites - Rates and mechanism of serpentinization and carbonation
- Permanent carbon dioxide sequestration in ocean sediments: flow-through reactor studies
Postdoc at Lamont working to understand what drives long-term climate variation on Earth. Particularly interested in water-rock reactions in ultramafic systems, clay formation, and organic carbon burial. More info: joshmurray-geo.github.io.
I went to The University of York, UK, and did a Physics BSc. My final year project was on the nucleation of freezing in supercooled water, supervised by Dr Richard Keesing. We scattered a laser through droplets of supercooled water to observed freezing as it was initiated by the application of an electric field.
Between 2009 and 2013 I did PhD in glaciology in the Department of Geography, Sheffield University, supervised by Dr Felix Ng. My thesis was entitled 'Modeling ice-dammed lake drainage'. I used mathematical models to study how water flows beneath glacier.
Between 2013 and 2016, was a Glacier Geophysicist at the British Antarctic Survey (BAS), Cambridge, UK. I was employed on a NERC-funded project led by Richard Hindmarsh. We used radar and mathematical models to study present-day and past ice flow in West Antarctica. I conducted two two-month field seasons in the Weddell Sea Sector of Antarctica.
In March 2016 my wife and I moved from the UK and I started my current position as Assistant Professor in the Department of Earth and Environmental Sciences, Columbia University, and the Lamont-Doherty Earth Observatory.
My research is concerned with obtaining a better understanding of glacial processes to improve predictions of ice-sheet evolution.
I advise a group of students and post-docs using remote-sensing, mathematical modeling and fieldwork to better understand glacial processes.

Joerg M. Schaefer
Joerg Schaefer is a Lamont Research Professor, Director of Lamont-Doherty Earth Observatory’s Cosmogenic Nuclide Group, a faculty member of the Department of Earth and Environmental Sciences (adjunct professor at DEES), and a senior fellow of the Center of Climate and Life at Columbia University. His key interests include how glaciers and ice-sheets respond to past and modern warming, how changing ice and related hazards, such as tsunamis and glacial lake outburst floods, impact environment and society and how science can assist in developing solution strategies for these climate-related challenges.
Schaefer founded the Lamont Cosmogenic Nuclide Laboratory in 2004, and his research group has become a world-leader in ‘Climate and Glacier Change’ science. Scientists in Schaefer’s Group apply cosmogenic isotope techniques to evaluate the response of ice on the Earth’s continents to past, modern and future warming. Schaefer, who is a climate geochemist, has advanced the cosmogenic dating method to the point where they can now determine whether a rock has been exposed by changing ice for thousands of years, hundreds of years, or just a few years. Schaefer and his team complement the isotope techniques with remote sensing approaches and cutting-edge ice-sheet modeling, to understand, and better predict, the accelerating changes of polar ice-sheets and mountain glaciers in past, present and future. Most recently, the NSF funded a large multi-million $, 5 year - 4 institution research program that Schaefer designed and leads, the GreenDrill project, to drill through the Greenland Ice Sheet (GrIS) at strategic locations and apply cutting-edge cosmogenic nuclide techniques to bedrock under the ice, to map the response of the GrIS to past warm periods.
Studying the impacts of these cryosphere processes on society, and creating multi-disciplinary networks to develop cross-cutting ideas how to respond to, how to find solutions to these paramount climate-related challenges, has become a recent focus area of Schaefer’s work. Schaefer loves to teach science, and is leading the development of the new ‘Climate Science Major’ program at Columbia together with Prof. Suzana Camargo and the DEES curriculum committee. This program consists of three coordinated Climate Science Majors, one within DEES (‘Climate System Major’), one shared with the ‘Sustainable Development’ program (‘Climate and Civilization’) and one (‘Climate Physics and Chemistry’) shared with the department of ‘Applied Physics and Math (APAM)’. Schaefer is actively engaged in Justice, Equity, Diversity and Inclusion efforts in US Geosciences, as well as in anti-harrassment and anti-bullying campaigns within the US science community.
Schaefer earned his Ph.D. in 2000 from the Swiss Federal Institute of Technology (ETH) Zurich, his thesis awarded with the ETH medal prize. He was a postdoctoral researcher at ETH before joining Lamont as a postdoctoral research fellow in 2001.

Dr. Joaquim Goes was born in Nairobi, Kenya, to parents who formed part of a large diasporic community from a Portuguese colony in India named Goa. Political turmoil forced them to return to Goa where he and his siblings completed their education. After finishing his Master’s degree in 1992 at the University of Bombay in India, Joaquim was offered a Doctoral fellowship by the Japanese Ministry of Education and he moved to Nagoya University, Japan. Clueless in a pre-internet age, he dived headlong into a new culture and language, and oved every bit of it from the sashimi and onsen to kanji.
After Japan lost its ocean color satellite, Joaquim changed the course of his research. Molina and Rowland had just won the Nobel Prize for their work on the formation of the Ozone Hole. Little was then known on how ocean biology would respond to excess solar UV radiation. Working with the late and world renowned geochemist, Prof. Nobuhiko Handa, Joaquim showed how enhanced exposure to UV radiation could profoundly impact phytoplankton photosynthesis and the metabolic compounds they produce.
Later, he pursued his Postdoctoral studies under the late Prof. Toshiro Saino developing a novel algorithm to estimate seawater nitrate from remote sensing. Fortuitously, during his stint as a postdoctoral fellow in Japan, Joaquim met Dr. Barney Balch at a Japan-USA workshop on ocean color in Hawaii in 2000 who invited him to Bigelow Laboratory, Maine after his stint in Japan ended. Once again he embarked on a new journey, this time in a land of lobsters and vast expanses of untouched land often covered in a foot of snow. A year into his Postdoc, Joaquim was appointed as a Senior Research Scientist.
In 2010, he felt the need for another adventure so he moved to the big city of New York. Joaquim is currently a Lamont Research Professor at Lamont Doherty Earth Observatory at Columbia University in the Palisades and his research focuses on understanding how ocean ecosystems and plankton are responding to climate change. He uses his background in biochemistry to study organisms at the cellular level and combines this with his expertise in ocean color remote sensing and coupled physical biological modeling to address large-scale climatic questions.
The projects that Joaquim works with are very diverse covering the physiology and productivity of marine phytoplankton, carbon cycling in the sea, climate impacts on marine ecosystems and socio-economic implications, microplastics in aquatic ecosystem etc. Funding for his work comes from NASA, NOAA, NSF, Gordon Betty Moore Foundation, Sultan Qaboos Cultural Centre, Hudson River Foundation.
Joaquim mentors undergraduates, graduates and postdoctoral students both in his laboratory at Columbia University and at sea, but he especially enjoys working the High School students some of whom have won National and International recognition for their work in his laboratory.
Joaquim has published over 120 peer reviewed papers. Some of his work has been featured in highly acclaimed newspapers, magazines and on Public Broadcasting Service. Joaquim hold a Doctor of Science degree in Ocean Biogeochemistry from Nagoya University, Japan and a Master’s degree in Microbiology, Bombay University, India. He loves music and played the bass in a rock band as a teenager.

I use laboratory experiments to investigate the feedback between deformation processes and material properties. My work includes use of microstructural tools (electron microscopy, mass spectrometry, and FT-IR spectroscopy) and in situ measurements (ultrasonic wave analyses, permeability, stress, and strain) to derive mathematical models of deformation phenomenon. My interests include reaction-driven cracking during carbon mineralization of rocks, hydrolytic weakening in minerals, and shock induced deformation of ceramics.
I am a geophysicist focussing on mapping the distribution of basalts with carbon storage potential along the US eastern coastline. New high-resolution aeromagnetic data will be used with seismic interpretation to constrain the geometry and depths of offshore basins and identify the presence of basalt flows.
I conducted my PhD at Imperial College London, which identified the characteristics and universality of magnetic anomolies in mature hydrocarbon reservoirs. I used rock magnetic techniques in conjunction with basin modelling and seismic interpretaion to constrain the petroleum migration history of the Wessex Basin, UK. I also designed a reaction path thermodynamic model to identify the boundary conditions for the formation of metastable iron sulphides associated with subsurface reservoirs.
I have a Glaciology and Atmospheric Sciences background with expertise in satellite and airborne remote sensing. The main area of my research include mass balance of ice sheets and ice shelves. I study physical processes that impact the mass balance and stability of ice sheets and ice shelves, ice-atmosphere and ice-ocean interactions using a combination of satellite remote sensing, airborne radar and laser altimeter, ground based measurements, and modeling.
I did my Ph.D in Atmospheric Physics from Indian Space Research Organization in 2007 where I worked on radiative transfer algorithms to retrieve marine aerosols from satellite data. After briefly working on estimating snow depth in the Himalayas, in 2007 I came as a postdoc to University of Alaska Fairbanks to work on mass balance of Alaskan glaciers using airborne laser altimetry.
In 2010, I came to Lamont-Doherty Earth Observatory to work on surface processes impacting surface mass balance of Antarctica. I am now an Assistant Research Professor and my work has evolved to include both surface and basal processes of ice sheets and ice shelves.

I am a water guy.
In my research, I try to understand the variability and changes in the water cycle at multiple spatial and temporal scales, and apply such understanding to water resources management.
I care about reproducible research. I believe in sharing knowledge and work to promote science to a broader audience. I love teaching and I do my best to instill research interests in students.
Before coming back to academia, I was an engineer, running water treatment plants in Qatar and Singapore. Having seen the bolts and nuts of water resources systems, and the problems they inherited from a larger scale, I appreciate the importance of systematic planning and operation. That triggered me to pursue a PhD in Engineering Systems and Design, with a focus on water resources management.
As I was working towards better water management for a better future, I realized that the key to the future lies in the past, and trees hold—in their rings—a treasure map that can lead us to that key. Since then, the weirdly wonderful world of tree rings has always fascinated me.
My current research focuses on determining the water content of rocks from earth’s upper mantle. This is of crucial interest to scientists studying the material properties of tectonic plates and magma formation.
Previously I worked at the American Museum of Natural History in New York City where I specialized in electron microscopy and 3D analysis with x-ray computed tomography.
Helga do Rosario Gomes (Maria Fatima Helga do Rosario Gomes) is from the state of Goa in India, famous for its beautiful beaches so it’s inevitable that she was drawn to oceanography from a young age. She graduated with a Ph.D. in Biological Oceanography from Bombay University and after research positions in Japan and in Maine, she has been a Research Scientist at Lamont-Doherty Earth Observatory, Columbia Climate School from 2010 onwards.
Her research interests in climate impacts on marine ecosystems and ocean biogeochemistry have led her to study the impact of UV radiation on phytoplankton photosynthesis in the Antarctic waters, the influence of the Amazon River continuum in biological sequestration of carbon dioxide and the rise of mixotrophy in the Arabian Sea. She uses her diverse expertise in biochemistry, microbiology and remote sensing to develop methods to assess primary productivity both at the cellular level and from space. Dr. Gomes is interested in large-scale climatic questions such as the impacts of the new and unusual planktonic blooms in the Arabian Sea, the effect of Arctic warming and ice melt on the American lobster, the impact of urbanization on wetland systems especially around the Long Island Sound and ocean acidification and deoxygenation of waters from harmful algal blooms.
With her colleagues she has been developing ocean monitoring and decision support systems tailored to meet needs for sustainable management of coastal resources in tropical countries experiencing climate change. Currently she is a co-PI of a recent Colombia University President Global Fund Award to develop a prototype Kenya Ocean Monitoring and Decision Support System for sustainable coastal resource management under climate change. She is a member of SCOR Working Group SCOR Working Group 165 “Mixotrophy in the Oceans – Novel Experimental designs and Tools for a new trophic paradigm (MixONET)”.

Dr. Gomes is a trustee and Science Advisor for Goa Chitra, Goa, India, an anthropological museum that preserves and showcases the culture and lifestyle of the people of the west coast of India. She advises them on research programs for overseas students and has held a series of classes on Climate change and rising sea level for coastal communities of Goa.
My research focuses on the viscoelastic properties, especially anelasticity, of polycrystalline materials. Rock anelasticity causes dispersion and attenuation of seismic waves. In order to interpret the seismic structures in the Earth, it is important to understand the effects of temperature, grain size, melt fraction, and dislocation density on rock anelasticity. For this purpose, I have so far taken experimental approaches to measure viscoelastic properties using rock’s “analogue” materials. At Univ. Tokyo in Japan, I used organic polycrystals and mainly studied the effects of temperature and partial melting on anelasticity. Here at Lamont, I am using ice polycrystals to investigate the effects of dislocations on anelasticity. Taking advantage of the analogue experiments, I attempt to understand the underlying physical processes common to general polycrystals including rock.
I'm a Ph.D. student in the Dyhrman lab with a background in ecology and biogeochemistry. I am currently interested in the physiological ecology of marine phytoplankton, including nutrient stresses and carbon metabolite formation. I use molecular 'omics and culturing approaches to answer questions about these topics.

My current research interests focus on studying the behavior of fault systems using the statistical analysis of earthquake catalogs, from the production of detailed catalogs of small magnitude earthquakes to their analysis and development of new models. The collective properties of the numerous, ever-occurring small earthquakes give information on the rheology of the faults, and more generally the properties of the crust, that hosted them. One of the most noticeable applications of this statistical approach is the search for temporal variations of statistical properties before large earthquakes that could help us identify their preparation phase.

Dylan is a Postdoctoral Research Scientist in the Climate School and Lamont-Doherty Earth Observatory at Columbia University. He is an archaeologist specializing in remote sensing applications and human-environmental interaction. Dylan's research interests primarily focus on human responses to hypervariable conditions. In particular, he's interested in how societal actions can influence environmental systems, and how people are impacted by unpredictable climatic conditions. Most of Dylan's work focuses on island and coastal regions and makes use of geospatial methods (e.g., remote sensing, GIS, network analysis) in conjunction with archaeological, ethnographic, and paleoecological data. Ultimately, his work seeks to further our understanding of how people interact with and are affected by their environment. Dylan's ongoing research seeks to understand the role that socioeconomic strategies play in long-term ecological change across landscapes. Specifically, his postdoctoral research focuses on how ecological systems are impacted by foraging, pastoralism, and agricultural activities. Dylan earned his Ph.D. in Anthropology in 2022 from Penn State. He also has an MA (2018) and BS (2017) in Anthropology and a BA (2017) in Geography from Binghamton University. Dylan currently serves on the Editorial Board of Archaeological Prospection as an Early Career Researcher.

David Goldberg is Paros Lamont Research Professor in Climate Science Research and Carbon Management. His interests focus on the integration of different technologies and cross-disciplinary approaches to develop achievable climate solutions. Goldberg received his undergraduate and MS degrees in earth and planetary sciences from the Massachusetts Institute of Technology, and his doctorate in geophysics and an MBA from Columbia University. He conducted post-doctoral studies at the Institute Français du Petrole in Paris and has been at Lamont-Doherty since 1985. He also currently serves as a Deputy Director of the Lamont-Doherty Earth Observatory, Associate Director of the Marine Large Programs division, Director of the Lenfest Center for Sustainable Energy, and a lecturer in the Columbia University Sustainability Science program.
David Porter is an Associate Research Scientist at the Lamont-Doherty Earth Observatory in the Climate School at Columbia University. He studies how the atmosphere and ocean drive changes in the ice sheets, and how the resulting changing sea level affects coastal communities. His research involves climate processes at high-latitudes, and is particularly interested in the interactions between different Earth System components. His expertise is at this intersection of traditional disciplines. At the ice-ocean interface, he studies how ice is melting in warming ocean waters, likely the most pressing question for the future of the Greenland and Antarctic ice sheets. Are warming ocean waters responsible for the increase in mass loss of marine-terminating glaciers worldwide? How stable are Antarctic ice shelves, especially the Ross Ice Shelf which holds back several meters of sea level rise? At the atmosphere-ice interface, he asks “what drives the newly-observed liquid water on the surface of the frigid Southern Continent?” And at the solid earth-ice interface, under the massive and ancient ice sheets themselves, he’s involved in projects to link geological controls on fast moving glaciers and ice streams.
Dave started his science career in meteorology at Rutgers University in New Jersey, fascinated both by the power of hurricanes Andrew and Allison but also playing in snow drifts dropped by potent nor’easters. Since that time, he has diversified his interests, advancing polar meteorology by modeling atmospheric changes to Arctic sea ice loss for his doctorate from University of Colorado at Boulder. Further broadening for his postdoctoral project at LDEO of Columbia University, he used new gravity-derived bathymetry from NASA Operation IceBridge to link ocean heat to glacier mass loss. Since then he has sailed aboard the US ice breaker Nathanial B. Palmer to the remote East Antarctic coast to map the seafloor and collect new water samples, and currently working with coastal communities in Greenland to link changes in the Greenland ice sheet to impacts on the built environment and social systems.
I am currently a Lamont Associate Research Professor at Columbia Climate School’s Lamont-Doherty Earth Observatory in Palisades, NY. In addition, I am a Columbia University Climate and Life Fellow leading a project on air pollution and climate change in Africa. I am also an affiliated scientist with the NASA Goddard Institute of Space Studies in New York, NY, and an air pollution advisor to the US State Department. Prior to Lamont, I worked as a Science, Technology, and Environmental Policy (STEP) postdoctoral research associate at Princeton University. I completed my PhD degree in May 2013 in Civil and Environmental Engineering from Carnegie Mellon University, under the supervision of Dr. Peter Adams. Outside of work, I enjoy sports, science, reading, and New York City living.
Daniel Bader is a Senior Staff Associate I at the Lamont-Doherty Earth Observatory. His primary responsibility is managing the Consortium for Climate Risk in the Urban Northeast (CCRUN), a NOAA RISA Project. He has extensive experience with preparing and communicating climate science information to policy makers, specifically in states across the Northeast. Prior to managing CCRUN, he was a programmer at the Center for Climate Systems Research (CCSR), tasked with developing climate scenarios to be used for adaptation planning. The data he has worked with is the foundation for climate resiliency planning efforts in New York City (through the New York City Panel on Climate Change), New York State, and across the National Aeronautics and Space Administration (NASA). His educational background includes a Bachelor of Science in Atmospheric Science from Cornell and Masters in Climate and Society from Columbia.
Dallas Abbott has worked in the areas of Marine Geology, Geophysics, Precambrian Geology, and Impact Geology. Over the past 13 years, Abbott has developed the microtechniques necessary to study the fine debris from oceanic impacts. Deep-sea impacts pose several problems. The first is a very restricted sample size compared to subaerial impacts. The second is a lack of large quartz grains in most settings, resulting in a reduced abundance of or no shocked quartz. Her collaborators and she have developed microtechniques to study oceanic impacts. They use the scanning electron microscope and analyses of thin sections of tiny grains to find and confirm impact ejecta.
Abbott has also learned how to separate out particulates from ice cores at ages of suspected Holocene impacts. They measured the highest concentration ever of marine diatoms in the GISP2 ice core. The diatoms are low latitude and originate from a source on a continental shelf with high biological productivity. Several other types of dust, including micrometer sized CaCO3 crystals, accompany the diatoms. The latter may have caused a dust veil and climate downturn that lasted for 18 months (Feb. 536 to June 537 AD). Some dust with both substantial Ni and K may be impact ejecta. They are still developing these microtechniques but they have already yielded some important scientific results. By combining proxies for continental dust with historical accounts of unusual dust storms, they have managed to date their ice core samples to within a calendar year. This allows us to tie our scientific results into the historical record-a mix that should attract students of both Earth Science and History. One accomplishment is documenting oldest primary native Fe ever found. Abbott and her collaborators found 1.6 Ga native Fe in the Chaibasa Formation in India. This is the worlds oldest primary native Fe by over a billion years.
I am interested in the relationship between stress, structure, and seismicity in volcanic environments, particularly how these factors evolve during volcanic intrusions. I develop software for the construction of high-fidelity catalogues of microseismicity from raw seismic data, including analysis tools for magnitude estimates, focal mechanisms, and seismic anisotropy, as well as analytical forward modelling tools for deformation and seismic anisotropy.
At LDEO, I am working as part of the AVERT (Anticipating Volcanic Eruptions in Real Time) project to develop and field test a rugged hardware/software system for multi-disciplinary monitoring of remote volcanic systems. We are currently operating a near-real-time network on Cleveland volcano, in the Aleutian arc, as well as supporting the efforts of the Alaska Volcano Observatory at nearby Okmok volcano. Data from our geodetic, seismic, magnetic, and imagery (both infrared and visible spectrum) instruments are transmitted via satellite back to our servers, where they are made immediately available via our web portal.
Dr. Nelson is a geochemist with expertise in basalt chemical weathering, aqueous geochemistry, and secondary mineral formation. She earned both an M.S. and a Ph.D. from Northwestern University, where her field-based research focused on basalt weathering in both subsurface and surficial settings in Iceland. She is researching carbon capture and storage technologies. Her current interests include in-situ carbon mineralization in basaltic reservoirs, as well as coastal and terrestrial enhanced weathering as climate change mitigation strategies. Currently, Dr. Nelson uses reactive transport modelling to optimize mineralization during carbon dioxide injections into basaltic rock. Her aim is to contribute to the scaling of this in-situ mineralization technology by specifically focusing on large-scale injections in offshore settings. When not working, Claire is usually skiing, biking, or indulging in NYC's abundance of live music.

Christopher Zappa is a Lamont Research Professor in and the Associate Director of Ocean and Climate Physics, and a Lecturer in Earth and Environmental Sciences. He attended Columbia University as an undergraduate and earned a Bachelor of Science in Mechanical Engineering in 1992. Prior to joining Columbia in 2003, he received his Masters in Engineering in 1994 and his PhD in Applied Ocean Physics in 1999 from the University of Washington, Seattle and completed his Postdoctoral Scholar Award at the Woods Hole Oceanographic Institution in 2003. He was an ONR Young Investigator from 2004-2007 and the 2017 Schmidt Ocean Institute 5th Anniversary Impact Award recipient. He was awarded a Fulbright Scholar in 2018 to study unoccupied aerial systems at the University of Napoli, Parthenope.
His research interests include air-sea interaction, air-sea gas exchange, ocean surface gravity-capillary waves, wind-wave interaction, wave dynamics and wave breaking, near-surface ocean and atmospheric turbulence, boundary-layer processes of heat, mass, momentum, and energy transport, infrared, multispectral, and polarimetric remote sensing, upper-ocean processes, polar ocean processes, coastal and estuarine processes. He has led a continuing evolution of the development of measurement systems for air-sea interaction, heat exchange and small-scale processes. He has developed an airborne infrared dual-imaging technique to characterize sea surface temperature variability at scales ranging from O(1m) to O(1km). He has worked to develop imaging techniques that use polarization of visible radiation to quantify the phase-resolved fine-scale ocean surface capillary-gravity waves. Currently, he is developing a multispectral infrared imaging system for the direct remote measurement of momentum and heat flux at the ocean surface (i.e., the viscous shear stress and thermal gradient in the aqueous viscous sublayer). Finally, he is a leader in unoccupied aerial systems (UAS) and their measurement sensing capabilities.
I joined the research staff at LDEO in 1968 and was Appointed Associate Professor in 1973 and Professor in 1977. I study the brittle deformation of the earth, both on the short term: earthquake physics, and the long term: fault mechanics. My work includes experimental rock mechanics, field studies of faulting, and theoretical studies. I have co-authored with students and colleagues over 300 papers on these subjects, and am the author of the leading treatise in this field, now in its third edition: The Mechanics of Earthquakes and Faulting, 3rd ed. Cambridge Univ. Press, 2019. Earlier editions were translated into Japanese and Chinese.
I am a Fellow of the American Geophysical Union and have been awarded the Murchison Medal of the Geological Society (London) and the Harry Fielding Reid Medal of the Seismological Society of America.
I am a seismology PhD candidate at the Lamont-Doherty Earth Obsevatory of Columbia University. My research focuses primarily on imaging subsurface structure on a tectonic scale using surface-wave methods. I am most interested in lithospheric structure and evolution, particularly at plate margins.
Science is an active process and I enjoy engaging with every step, from data collection in the field to science communication and outreach beyond the classroom.
My research explores the way that micro-features control macro-behavior. Defects in the structure of crystalline materials, such as impurities, dislocations, grain boundaries, and partial melt, all affect the way that seismic waves are damped in the mantle, for instance, or how tidal energy is turned into heat within an icy moon's outer shell. In order to better interpret seismic data and provide better constraints for goephysical modeling, I design experiments to isolate and scrutinize the underlying microphysics of defect-controlled processes such that resultant laboratory data can be scaled up to macroscopic settings. With material properties being the constant element, my work spans a variety of time and length scales and geologic contexts: from the deep earth, to the cryosphere, to the outer solar system.

Celeste is a paleoceanographer and geochemist with an interest in tropical ocean dynamics during the last few glacial and interglacial periods. She uses proxies for past climate and ocean conditions from marine sediment cores, such as foraminifera, in her research. Her current work focuses on the eastern equatorial Pacific thermocline and the El Niño-Southern Oscillation during the last interglacial period before the present.
She also enjoys teaching and mentoring undergraduate students, including at Columbia and Barnard. Any aspiring paleoceanographers are welcome to contact Celeste.
My research focuses on marine geology and sedimentation processes to understand earthquake and tsunamis, sea-level changes, climate and the impact of anthropogenic activities in the local rivers and estuaries such as the Hudson and Long Island Sound. I have also studied the effects of extra-terrestrial impact events as the one that happened 35 million years ago in what is today Chesapeake Bay in Maryland and Virginia. My driver for conducting research is the discovery of the unknown. Very little is known about the ocean floors in proportion to their huge coverage of the Earth 70%. Indeed there are discoveries in every expedition I participated. The beauty of studying sediments is that in the submarine environment they tend to be deposited and not disturbed as on land. So the history of events in preserved back in time for millions of years. We learn about the past to understand the future and the sediments are great sources of information. As one of the precursors of the field of submarine paleoseismology I study earthquakes and tsunamis under the sea. This work began in Turkey in 1999 after catastrophic earthquakes caused thousands of casualties and much destruction. As Pi and CoPi, I have lead expeditions to study the M7.0 2010 and M7.2 2021 Haiti earthquakes as part of RAPID Responses, and I am studying the disastrous M 9.0, 2011 Japan earthquake and tsunami as part of the International Ocean Drilling Expedition to the Japan Trench.
The burning of fossil fuels releases gases into the atmosphere creating a greenhouse effect. So the Earth is getting warmer and so are the oceans. As a result, mountain glaciers and ice sheets are melting and the oceans are warming. These processes lead to a rise in sea-level that is accentuated by thermal expansion of the ocean waters. Warmer oceans lead to increased storm activity and greater storm surges that are penetrating further landwards and maintaining their energy through longer periods of time. These factors threaten our heavily populated cities. By studying the sedimentation record I learn what climate and sea-level were in the past and hope to help understand their impact in the future.

Brendan Reilly is an Assistant Research Professor at Columbia University's Lamont-Doherty Earth Observatory. As a seagoing geological oceanographer, he explores the deep sea to uncover clues about how the Earth works. Brendan has worked in diverse locations, from the Arctic to the Indian Ocean.
Brendan is also the Director of the Lamont-Doherty Core Repository, a massive collection of deep sea sediment cores and other seafloor samples from around the world. These cores provide researchers with invaluable insights into the Earth's past, allowing us to better understand how our planet has evolved over time.
Brendan's research often focuses on how ice sheets, like those in Greenland and Antarctica, have changed in the past using marine sediment cores. He is particularly interested in paleomagnetism, or the study of the ancient geomagnetic field as recorded in geologic materials, as a tool to better understand these archives. By analyzing the geomagnetic signals archived in sediment cores, Brendan can determine geologic time and make connections between otherwise disparate archives.
Brendan Buckley holds the position of Lamont Research Professor, and has been a long-time member of the Tree Ring Lab at the Lamont-Doherty Earth Observatory of Columbia University (LDEO). While he has worked in locations around the globe, Buckley has been one of the pioneers of tropical dendroclimatology, having produced the longest and best replicated records of absolutely dated tree ring sequences from Southeast Asia. Among his most important discoveries were the identification of two key periods of drought that coincided with the two most tumultuous periods of the past millennium over Southeast Asia – the Angkor droughts of the late 14th/early 15th century, and the Strange Parallels Drought of late 18th century, respectively. He continues this important work by using new methods to develop discrete seasonal reconstructions of regional hydroclimate, including measures of the strength of summer and winter monsoons, as well as the “shoulder” seasons that lead into and out of them, over the past millennium. Buckley is a proponent of interdisciplinary research, working with historians, archaeologists, geochemists and atmospheric scientists. Along with his research in the Asian tropics, he has a long history of research in the North American boreal forests, having conducted some of the first dendroclimatic forays in northern Labrador, Canada, and North America’s northernmost trees in the Firth River of Alaska. He was also instrumental in developing the longest temperature reconstructions from the Southern Hemisphere as part of his PhD research in Tasmania and New Zealand.
Buckley received his undergraduate degree in Physical Geography from Plymouth State College in New Hampshire, a Masters degree from Arizona State University in Tempe, and his PhD from the Institute of Antarctic and Southern Ocean Studies (IASOS) at the University of Tasmania, Australia. He held Post-doctoral positions at the University of Auckland, New Zealand and at the Lamont-Doherty Earth Observatory of Columbia University, before commencing his current LDEO position in 1999.
I am a solid-earth geophysicist and my research focuses on characterizing the structure and evolution of the Earth’s lithosphere. In particular, I seek to understand the feedbacks between stress, metamorphism, deformation, topography, climate, and mass/fluid fluxes along plate boundaries and mature tectonic settings. I am interested in the manifestation of these processes spatially from the upper mantle to the surface, and temporally from the creation of new lithosphere to its destruction at subduction zones.
My interdisciplinary approach is founded in the imaging, interpretation, and inversion of active-source seismic data, combined with complementary data types, such as passive seismic imaging, geologic observations, and geochemical analyses. With my research, I aim to improve our knowledge of fluid-tectonic interactions within the lithosphere, and the consequential hazards from earthquakes, tsunamis, and volcanoes. I am currently working with new seismic data collected along the Cascadia subduction zone to better understand these tectonic processes.
My passion for the geosciences was instilled during my early youth growing up in Colorado, where I was exposed to incredible exposures of geologic formations. This curiosity led me to begin my academic adventure at Western Colorado University, where I received B.S. degrees in Geology and Mathematics. At Western, I was emersed in the beauty of the Gunnison valley and became fascinated with the stratigraphic record of the Ancestral Rockies. Field trips to the Moab region along the Colorado Plateau, skiing on the Crested Butte laccolith, and floating rivers carving through Precambrian basement rocks further solidified my passion for the outdoors and connection to the geosciences.
Following my time at Western, I pursued a PhD at the University of Texas at Austin Institute for Geophysics. At UT, I infused my background in geology and mathematics by developing skills in marine geophysics to study plate tectonic processes. I was fortunate to interact with a diverse range of geoscientists across the globe, acquiring marine seismic data in New Zealand, deploying seismometers in the Kenyan Turkana rift, and venturing to southern Spain to collect samples for geochronological analyses. My PhD research targeted two fundamental tectonic process – continental rifting and subduction initiation. I analyzed active-source seismic data along the Eastern North American Margin and Puysegur Margin, New Zealand, to investigate the mechanisms that enable lithospheric rupture during the breakup of continents and formation of subduction zones. After graduating from UT, I started my current position at Lamont-Doherty Earth Observatory as a Postdoctoral Research Scientist.
My research is focused on utilizing the geochemistry of corals, microfossils and marine sediments to document past oceanographic and climate conditions over a range of time-scales from sub-annual to glacial-interglacial. In addition to my role as a Lamont Research Professor, I also serve as Director of the Lamont-Doherty Stable Isotope and Trace Element Laboratory, New Core Lab, and Director and teacher in the M.S. in Sustainability Science Program. I came to Lamont in 2011 after 16 years as a Professor in the Department of Atmospheric and Environmental Sciences at the University at Albany-SUNY.
Bennett Slibeck is a PhD candidate at Columbia University’s Lamont-Doherty Earth Observatory (LDEO), where he studies dinosaur footprints, the End Triassic Extinction, and global environmental change through the Mesozoic. Bennett works with Dr. Paul Olsen and was awarded the NSF graduate research fellowship in 2023, to aid in the completion of his degree. In 2021, he designed and implemented the creation of the Quantitative Morphometrics Computing Facility at LDEO, enabling his research into high resolution digital modeling, with a special focus on ichnofssil photogrammetry. His master’s research focused on The End Triassic Extinction and The Rise of Dinosaur Dominated Ecosystems in the Newark Basin, with a special focus on the use of “ichnocladistics” as a conceptual framework for interpreting the trace fossil record.
As an indigenous scientist, Bennett is also keenly focused on environmental justice, and is a part of ongoing collaboration between Columbia University and the Navajo Nation to understand the distribution of geogenic groundwater contaminants in the nations water supply. CLEANN (the Collaboration to Lower Arsenic Exposure on the Navajo Nation) sits at the intersection of public health, hard rock geology, and environmental justice. He firmly believes that it is incumbent upon all of us to repair the damaged relationships between scientists and indigenous communities and hopes that his own continued efforts in this field will enrich the world around him.
Bennett considers himself a storyteller above all else, and notes that paleontology provides our best framework for navigating an increasingly volatile future. Through his career as a scientist and educator, Bennett hopes to inspire people to see the deeply intrinsic sense of wonder gained through careful observation of any natural system, such that they carry that wonder with them into a more beautiful world.
Dr. Beizhan Yan is an Adjunct Associate Professor of International and Public Affairs and a Lamont Associate Research Professor at Lamont-Doherty Earth Observatory (LDEO). His Ph.D. study at RPI (2000-2004) focused on the source apportionment of polycyclic aromatic hydrocarbons (PAHs) in the Hudson River. After two years of postdoc in Idaho National Laboratory, he joined Washington University in St. Louis to study nanoscale size effects on biogeochemical processes for environmental bioremediation. At LDEO, he has established an Environmental Organic Geochemistry Lab with ability to extract, isolate, and identify organic contaminants and biomarkers from environmental and biological samples.
He has successfully traced metals and aromatic hydrocarbons in the waters and air of NYC and linked the exposures of these air pollutants to pediatric asthma outcomes. He is also leading a collaborative study to examine the association between pediatric respiratory outcomes and air pollutants (including PM2.5 and black carbon, VOCs) in Beijing China. To determine possible impacts of hydrofracking on environment stresses (e.g., noise and air and water pollutions), psychological stress, and health outcomes, he is leading a collaborative study in Pennsylvania. He is also conducting the ecological impact of microplastics in estuaries and oceans.
Bärbel Hönisch is a Professor of Earth and Environmental Sciences, and specializes in Paleoceanography. Her primary research interests are the linkages between atmospheric carbon dioxide and climate in the past, including the validation and application of paleoproxies in marine archives.
The focus of Dr. Chadwick’s research is to explain how river systems evolve, shape landscapes, and respond to our rapidly changing world. He has 10+ years of experience quantifying fluvial processes using a blend of theoretical modeling, remote sensing, laboratory flume experiments, and geologic field techniques; and has contributed to interdisciplinary field campaigns on the Mississippi River (LA, USA), the Koyukuk River (AK, USA), the Yellow River (China), and the Ganges-Brahmaputra river system (Bangladesh). His work is defined by two common threads. First, he seeks answers to fundamental questions about the origin and organization of landscapes on Earth and other planets. Second, he investigates how rivers today are responding to human activities and global climate change—especially in our vulnerable coastal zones and cryosphere—to address twenty-first-century concerns about geologic hazards and environmental sustainability. His work interweaves these fundamental and practical threads in targeted research topics, including 1) the evolution of deltaic landscapes, 2) the mobility of river channels, and 3) the connection between rivers, oceans, and the shallow subsurface.
A seismologist, Arthur Lerner-Lam has led scientific expeditions in the Middle East, Europe, Central and South Asia, the Southwest Pacific, and throughout the United States. Over the last 20 years, he has lectured and written widely on natural hazard risk identification, assessment and management. At Columbia, Lerner-Lam directs the masters programs in sustainability science and environmental science and policy. These programs provide a broad and quantitative understanding of the environment, including Earth’s climate, and foster critical thinking about the public policies and private sector management principles needed for resiliency and sustainability. With colleagues from political science, economics and international affairs, Lerner-Lam also has developed related curricula on sustainability management and sustainable investing suited for intensive executive education certificate programs. Lerner-Lam received his undergraduate degree in geological sciences from Princeton University, and his doctorate in geophysical sciences from the Scripps Institution of Oceanography at the University of California, San Diego. He has held Post-doctoral positions at Scripps and the Massachusetts Institute of Technology, and has been at Lamont-Doherty since 1985. He has been on numerous scientific advisory committees and editorial boards including as a member on the Federal Scientific Earthquake Studies Advisory Committee for the U.S. Geological Survey, as a consultant to the U.S. Trade and Development Agency and as a contributing author to the U.N.’s Global Risk Update and the World Bank’s Global Hotspots Report. He has consulted on environmental and natural hazard resilience for the governments of Haiti, the Dominican Republic, Chile, India, China, Thailand, Turkey and Venezuela. He has testified before the U.S. Congress on the Nation’s preparedness for natural disasters.
I am a field-going physical oceanographer, an observationalist. My research is directed at the ocean's stratification, circulation and mixing and its role in Earth's climate system. I study the transfer of heat and freshwater within the ocean and between the ocean, cryosphere and atmosphere. I view the ocean as a global system, with specific attention to interocean exchange and to ventilation of the deep ocean interior through sea-air-ice interaction. Comparison and extension of observational data with model results are an increasingly important part of my research. Historically much of my research deals with the Southern Ocean and South Atlantic, but research within the warmer waters of the Maritime Continent and Indian Ocean now compose most of my research program. Recently my focus is on the role of the ocean mesoscale in the transfer of heat and freshwater to compensate for net sea-air flux. I tend to go to areas that have been neglected by the research community, but have the potential of being key players in the global system.
Arianna is a Ph.D. candidate at the Lamont-Doherty Earth Observatory of Columbia University in the City of New York. Her research focuses on precipitation trends and variability in southeastern South America (southern Brazil, Paraguay, Uruguay, and northeastern Argentina) in observations and climate model simulations. Her goal is to better understand the drivers of past and present precipitation change so that we can better constrain future projections of precipitation. Arianna is co-advised by Jason Smerdon at Lamont-Doherty Earth Observatory of Columbia University and Park Williams of University of California, Los Angeles.
Dr. Anne Bécel's research focuses on characterizing the seismic structure of the Earth’s crust and uppermost mantle to better understand major processes that are taking place along active plate boundaries such as transform faults or subduction zones but also at rifted passive margins and ocean basin settings. To investigate these processes, she primarily uses marine active-source seismology. Her research at Lamont has mainly focused on the study of the Alaska Peninsula and Hellenic subduction zones with an emphasis on assessing specific risks such as large earthquakes and associated tsunamis and the development of the Eastern North American continental rifted margin.
Angela Slagle is a Research Scientist at Lamont-Doherty Earth Observatory of Columbia University. Her work focuses on petrophysical measurements as a means of characterizing sub-seafloor sediments and rocks, applied to a range of projects and geologic environments. Her current projects include studies of carbon sequestration in marine basalts (western Atlantic, Cascadia region in NW Pacific); cyclicity in physical properties as a response to Earth processes (Maldives Inner Sea); and integration of core, downhole logging, and seismic properties (various locations). Angela received a Ph.D. in Marine Geology and Geophysics from Columbia University.
Over the last ten years, she has sailed on eight research expeditions for the Integrated Ocean Drilling Program and International Ocean Discovery Program (IODP), as well as a number of research cruises on UNOLS vessels.

I am an aquatic ecologist and oceanographer with broad interests relevant to basic and applied issues in coastal marine systems, estuaries, rivers and lakes. Much of my research has focused on studying the growth and physiology of planktonic microorganisms (planktonic algae, protist microzooplankton, invertebrate zooplankton, and bacteria). I use a holistic perspective that encompasses how planktonic organisms interact with their physical/chemical environment, how they interact with their competitors and predators, and the implications for their population dynamics.
Planktonic organisms form the base of most aquatic food webs, and thus, the processes that regulate their populations also directly affect the abundance, diversity, and activities of higher trophic-level organisms. Plankton also play critical roles in aquatic biogeochemistry, such as fluxes of carbon and nitrogen. In addition, interactions within the community of planktonic organisms relate directly to applied, water-quality issues such as nutrient pollution and eutrophication, sewage pollution, harmful algal blooms, and hypoxia.
My research approach links hypothesis-driven, controlled laboratory experiments with small-scale field manipulations and field observations. Such research is inherently interdisciplinary, connecting cell biology and physiology with ecology, and physics and chemistry of the environment. I am always open to new and interesting ways to apply my expertise.
At Lamont, I am part of two main efforts: the Marine Geoscience Data System (MGDS) which provides access to marine geoscience data, and the GeoMapApp development team for which I help guide functionality and enhancements, run workshops and webinars, and add new data. For a while, I also worked on providing content for the EarthObserver and PolarExplorer:Sea-Level apps. I enjoy running outreach and education events and mentoring summer interns. I have interacted with educators at all levels and I studied for a masters degree from Teachers College to better understand the educational context.
Before coming to Lamont, I spent eight years at Scripps Institution of Oceanography in California. There, I followed my research interests in geodynamics, participated in nine sea-going research cruises, and worked in the SIO Geological Data Centre. Also, as part of the international GEBCO project, I worked on generating digital elevation models from echo-soundings and contours for about one-quarter of earth's oceanic area.
I have a degree in geology-geophysics from Durham University (UK) and a doctorate from the University of Oxford. My thesis topic was a study of tectonics and geodynamics in the south-central Pacific area and involved the analysis of shipboard gravity and bathymetry and the construction of satellite-derived geoid and free-air gravity data.
I like building a sense of community and have been on the Campus Life Committee, most recently as its chair, and like working on things to bring about positive change. For many years, I have organised the annual Lamont Bike-to-Work Day event. When not working, I like hiking in the mountains - the Alps are hard to beat, playing tennis, going on walks with my dog, and enjoying tasty meals.

Allison Franzese is an Associate Professor at CUNY Hostos Community College, where she teaches courses in Chemistry and Earth and Environmental Sciences. Her research activities take place at both Hostos and Lamont and involve the application of isotope geochemistry to paleoceanography. An overarching theme of her research is how the “Global Conveyor Belt” or thermohaline circulation (THC) was different in the past, with a particular focus on how the surface return flow of the THC has changed over millenial-scale, glacial-interglacial, and longer timescales.
I joined Lamont as a Systems Analyst/Programmer in January 2023. I work on USAP-DC, R2R, and GeoMapApp.
Prior to joining LDEO, I received a double Bachelor of Science in Computer Science and Math and a Master of Science in Computer Science from Binghamton University, with some professional software engineering experience in between. My master's thesis is entitled Compiler-Directed Regulation Enforcement for Unmanned Aerial Vehicles.
When not working, I enjoy baseball, skiing, and live music, often playing vibraphone at jazz jam sessions in the New York City area.
Alex N. Halliday is the founding dean emeritus of the Columbia Climate School. He joined the Earth Institute in April 2018, after spending more than a decade at the University of Oxford, during which time he was dean of science and engineering. With over 400 published research papers, Halliday has been a pioneer in developing mass spectrometry to measure small isotopic variations in everything from meteorites to seawater to living organisms, helping to shed light on the birth and early development of our solar system, the interior workings of the Earth, and the processes that affect Earth’s surface environment. His scientific achievements have been recognized through numerous awards, including the Murchison Medal of the Geological Society, the Bowen Award and Hess Medal of the American Geophysical Union, the Urey Medal of the European Association of Geochemistry, and the Oxburgh Medal of the Institute of Measurement and Control.

As a professor in Columbia’s Department of Earth and Environmental Sciences, Halliday divides his time between Columbia’s Morningside campus and his geochemistry lab at Lamont-Doherty Earth Observatory.
My current research focuses on ways to reduce the impact of the environment on human health. For two decades, I coordinated earth-science and mitigation efforts under Columbia’s Superfund Research Program on the origin and health effects of elevated levels of arsenic in groundwater. A theme that runs through this and other ongoing projects, e.g., concerning fluoride in groundwater in India, bauxite dust in Guinea, or soil contaminated with lead from mine-tailings in Peru, is that patterns of contamination are spatially very heterogeneous. This complicates prediction but often also points the way to mitigation when the hazard can be mapped. For this reason, I am a firm believer in the more widespread use of field kits by non-specialists to reduce exposure to environmental toxicants, particularly in developing countries. I collaborate with public health and social scientists to evaluate how such kits can be deployed at scale and have published over 180 peer-reviewed papers on this and other environmental topics. I hold a research professor appointment at Lamont-Doherty Earth Observatory and am a member of the Earth Institute faculty at Columbia University.
Alberto Malinverno received a degree in geology at the University of Milano, Italy, in 1981 and a Ph.D. in geology at the Lamont-Doherty Earth Observatory (LDEO) of Columbia University, New York, in 1989. After graduating, he spent three years at LDEO as a post-doctoral scientist and research scientist, participating in a total of twelve marine geology and geophysics seagoing expeditions. In 1992 Alberto joined the Schlumberger-Doll Research center in Ridgefield, Connecticut, where he worked on the quantifying uncertainties in the inversion of borehole measurements. He returned to Lamont in 2005 as a principal research scientist at the LDEO Borehole Research Group. As a logging scientist, he participated in five scientific drilling expeditions on the US drilling vessel JOIDES Resolution (North Cascadia margin, Bay of Bengal, Equatorial Pacific, and twice on the Costa Rica Pacific margin). Alberto is now a Lamont Research Professor and an adjunct professor at the Department of Earth and Environmental Sciences of Columbia University, where he teaches "Quantitative Methods of Data Analysis" (EESC G6908).

Adam H. Sobel studies weather and climate, with a focus on extreme weather events and a particular interest in the tropics. Phenomena include tropical cyclones, intraseasonal variability, precipitation, severe convection, and climate change, as well as a substantial effort in recent years in climate risk and impacts. Sobel’s research spans basic and applied prediction and risk assessment, and uses observations, theory, and numerical simulations with models spanning a hierarchy in complexity. He is particularly interested in the interactions between turbulent deep convection and large-scale atmospheric dynamics, as these are key to the qualitative and quantitative understanding and prediction of many modes of atmospheric behavior, including extreme precipitation events. He has developed novel methods for diagnosing these interactions, connecting high-resolution explicit simulations of cloud systems to simple theoretical representations of large-scale dynamics in order to extract essential mechanisms and understand the connections between weather and climate. In another line of work, with colleagues in both academia and the insurance industry, Sobel has been developing hybrid statistical-dynamical models, combining mechanistic understanding with inference from observational data, to assess the risk of rare but extremely damaging extreme weather events, particularly tropical cyclones, but also tornadoes and hail, extreme precipitation, and others.
Sobel also has a strong interest in science communication. He has written many op-eds for the mainstream media, as well as a book, Storm Surge (Harper-Collins, 2014) about Hurricane Sandy. Currently he hosts a podcast, Deep Convection, featuring wide-ranging conversations with other climate scientists.
Sobel received a BA in physics and music from Wesleyan in 1989 and a PhD in meteorology from the Massachusetts Institute of Technology in 1998. He has received the Meisinger Award (2010) and Louis J. Battan Author’s Award (2014) from the American Meteorological Society, the Ascent Award from the Atmospheric Sciences Section of the American Geophysical Union (2014), and the Lamont-Doherty Award for Excellence in Mentoring (2010).
