Patrick Alexander is an Associate Research Scientist in the Marine Geology and Geophysics division at the Lamont-Doherty Earth Observatory. He is a cryospheric scientist focusing on interactions between ice and climate. He incorporates remote sensing and in situ measurements with global climate models and regional climate models to study ice-climate interactions, particularly interactions between climate and polar ice sheets, with the goal of understanding the future impact of climate change on sea level rise. Prior to his current position, Patrick was a Postdoctoral Research Scientist at Lamont and a Postdoctoral Research Fellow at the NASA Goddard Institute for Space Studies. He earned his undergraduate and master's degrees in environmental engineering from Columbia University, and his doctorate from the Graduate Center at the City University of New York.
