Dr. Waleed Abdalati / Oceans and Ice Branch Head, NASA Goddard Space Flight Center

Dr. Abdalati is head of the Oceans and Ice Branch at NASA's Goddard Space Flight Center, where he conducts research on high-latitude glaciers and ice sheets using satellite and airborne instruments. He has led or participated in 8 field expeditions to remote regions of the Greenland ice sheet and the ice caps in the Canadian Arctic. From 2000 to the present, he has been Manager of NASA's Cryospheric Sciences Program, overseeing NASA-funded research efforts on glaciers, ice sheets, sea ice, and polar climate. For the last four years he has served as Program Scientist for NASA's Ice Cloud and land Elevation Satellite (ICESat), which which has as its primary objective understanding changes in the Earth's ice cover. Dr. Abdalati received his Ph.D. from the University of Colorado in 1996 and worked as a research scientist at NASA's Goddard Space Flight Center from 1996 through 2000. In 1999 he received the Presidential Early Career Award for Scientists and Engineers.

Dr. Ted Scambos / Lead Scientist at National Snow and Ice Data Center, University of Colorado

Dr. Scambos has worked at the University of Colorado's National Snow and Ice Data Center (NSIDC) since 1993, after receiving his Ph.D. at University of Colorado in Geology in 1991 and working as a post-doctoral contractor for NASA between 1990 and 1993. His primary research interests are Antarctic glaciology and the use of satellite data for studying the Earth's ice. Dr. Scambos has been on seven expeditions to the Antarctic, seeking to measure changes in ice mass balance, the history of ice flow, or to validate satellite sensor measurements. Dr. Scambos is the current chair of the McMurdo Area Users Group, and an associate Science Editor for the Journal of Glaciology.

Dr. Josefino C. Comiso / Senior Research Scientist, NASA Goddard Space Flight Center

After receiving a Ph.D. degree in physics at UCLA, Dr. Comiso worked as a research associate at the University of Virginia and later joined the Computer Sciences Corporation as a senior research analyst doing contract work with NASA. In 1979, he joined NASA Goddard Space Flight Center where he has been working first as a physical scientist and currently as a senior research scientist. At Goddard, his primary interest has been the study of polar processes and the detection of changes in the sea ice cover and surface ice temperatures. He has been the chief scientist in two aircraft missions funded by NASA in both polar regions, the principal investigator in many polar field programs, and a team member of the EOS-Aqua/AMSR-E and ADEOS-2/AMSR instruments. He is the originator of the Bootstrap Algorithm for sea ice and is the author or co-author of three books, several book chapters, and more than 90 peer-reviewed journal articles.
