Warren D. Sharp was born in 1952 in Berkeley, California. Sharp received both his B.A. (1974), and his Ph.D. (1984) in Geology from the University of California at Berkeley. His doctoral research involved development and application of K-Ar and U-Pb geochronometry to the formation of continental crust via plate tectonics processes. He accepted a faculty position in the Department of Earth and Space Sciences, State University of New York at Stony Brook, where he taught and established a research program centered on 40Ar/39Ar geochronometry applied to problems in continental crustal evolution. Since coming to the Berkeley Geochronology Center (then Institute of Human Origins) in 1992, his research has focused on providing a time-axis for significant geologic processes and events over the last ~ one million years, including active volcanism, glaciation, paleoclimatic change and active faulting. In particular, he has developed innovative applications of uranium-series dating to silica and carbonate soil components to provide ages for geologically youthful surfaces and strata in order to elucidate human physical and cultural evolution, relations between regional and global climate change, and rates of crustal deformation. He serves on the editorial board of Quaternary Geochronology, as co-leader of the International Quaternary Association’s Drylands Dating Sub-Commission, and as Associate Director of the BGC.
