Ellen Mosley-Thompson uses the chemical and physical properties preserved in ice cores collected from the polar ice sheets and high mountain glaciers to reconstruct the Earth’s complex climate history. She has led nine expeditions to Antarctica and six to Greenland to retrieve ice cores. She served as the principal investigator and field team leader for the ice core drilling project on Bruce Plateau (Antarctic Peninsula) which was part of LARsen Ice Shelf System Antarctica (LARISSA), a U.S. contribution to the International Polar Year. Areas of special interest include paleoclimatology, abrupt climate changes, glacier retreat, Holocene climate variability and contemporary climate change. She joined the Ohio State faculty in 1990 and became director of the Byrd Polar Research Center in 2009. Mosley-Thompson is a member of the National Academy of Science, a member of the American Academy of Arts and Sciences and a fellow of the American Geophysical Union. She was awarded the Benjamin Franklin Medal in 2012. Twitter
