Indrani Das

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 also work on paleo observations of accumulation rates and climate history of Greenland ice sheet. I am a co-PI on the International Thwaites Glacier Collaboration (NSF-NERC ITGC) and work on integrating remote sensing observations and ice sheet models to understand basal processes and conditions at the bed. I serve on National Academies on Sciences, Engineering and Medicine and a council member of the International Glaciological Society.
