Ellen Mosley-Thompson is an internationally respected expert examining the effect of global climate change on the world’s glaciers. She is a Distinguished University Professor in the Department of Geography and director of the Byrd Polar Research Center at The Ohio State University. She has made significant contributions to understanding Earth's climate history using chemical constituents and physical properties preserved in its glaciers and ice sheets. These records provide a critical historical context for assessment of contemporary climate changes and rigorous constraints on regional and global forcing mechanisms. She has led nine expeditions to Antarctica and six to Greenland to retrieve ice cores and in 2010 led an ice core drilling project on Bruce Plateau (Antarctic Peninsula). Her areas of special interest include abrupt climate change, glaciology, glacier retreat, and Holocene climate variability. She is a member of the National Academy of Sciences and the American Academy of Arts and Sciences and is a fellow of the American Association for the Advancement of Science. She has published over 120 peer-reviewed scientific papers, and her work has been supported by over 50 research grants. She holds a B.S. degree from Marshall University and M.A. and Ph.D. degrees from The Ohio State University.
