Eric J. Rignot is the Donald Bren, Distinguished and Chancellor Professor of Earth system science at the University of California, Irvine, and a Senior Research Scientist for the Radar Science and Engineering Section at NASA's Jet Propulsion Laboratory. He studies the interaction of the polar ice sheets in Greenland and Antarctica with global climate using a combination of satellite remote sensing (synthetic-aperture radar interferometry), airborne remote sensing (depth sounding radar, gravity), understanding of physical processes controlling glacier flow and ice melt in the ocean, field methods (multibeam echo sounding, CTD, AWS), and climate modeling (ISSM, MITgcm). He was elected at the National_Academy_of_Sciences in 2018. Source: Wikipedia (en)
