Biographical Sketches of Committee Members

Donald J. DePaolo, Chair, is the Class of 1951 Professor of Geochemistry at the University of California, Berkeley; director of the Center for Isotope Geochemistry; and director of the Earth Sciences Division at the Lawrence Berkeley National Laboratory. He received his Ph.D. in geology from the California Institute of Technology. Dr. DePaolo’s research interests are in the application of radiogenic isotope geochemistry and principles of physics and chemistry to problems in geology, geophysics, and environmental science. He has served on several advisory committees concerned with the geosciences, including the National Research Council’s (NRC’s) Board on Earth Sciences and Resources and its Geodynamics Committee, and has chaired numerous professional society, advisory, and university visiting committees. Dr. DePaolo is the recipient of many awards for his contributions to the geochemical and geophysical sciences, including the American Geophysical Union’s Macelwane Award, the Geochemical Society’s F.W. Clark Medal, the Geological Society of America’s Arthur L. Day Medal, and the European Association of Geochemistry’s Harold Urey Medal. He is a member of the National Academy of Sciences and the American Academy of Arts and Sciences.


Thure E. Cerling is Distinguished Professor of Geology and Geophysics and Distinguished Professor of Biology at the University of Utah. He received his Ph.D. in geology from the University of California, Berkeley. His research concerns near-surface processes and the geological record of ecological change. Of particular interest are isotope physiology and paleodiets of mammals, soils as indicators of climatological and ecological change over geological timescales, and landscape evolution over the last several million years. Dr. Cerling has served on several NRC solid-earth committees, including the Board on Earth Sciences and Resources, the Geodynamics Committee, and the U.S. National Committee for the International Union for Quaternary Research. He is member of the U.S. Nuclear Waste Technical Review Board, a fellow of both the American Association for the Advancement of Science and of the Geological Society of America, and a member of the National Academy of Sciences.


Sidney R. Hemming is an associate professor in the Department of Earth and Environmental Sciences at Columbia University. She earned her Ph.D. in geology from the State University of New York, Stony Brook. Her research focuses on paleoceanography, paleoclimate, tracer studies, and geochemistry of sedimentary rocks. Several of her current projects deal with reconstructing ocean circulation patterns at different times, including periods of abrupt climate change. Other projects aim to understand the role of ice sheets in regional and global climate change, including studies of the North Atlantic and circum-Antarctic oceans and Mono Lake. Dr. Hemming is deputy director (education liaison) of the Cooperative Institute for Climate Applications and Research, a research partnership on climate variability and change sponsored by the National Oceanic and Atmospheric Administration and Columbia. She is a member of the American Geophysical Union and the
