Dr Hamilton has a geophysical engineering degree from Colorado School of Mines, and M.A. and Ph.D. degrees in geophysics from the University of California at Berkeley. Berhane Asfaw (NAS) is a palaeoanthropologist who manages the Rift Valley Research Service. Dr. Asfaw has completed extensive survey work on the eastern and western sides of the Awash River in Ethiopia. He was instrumental in explo- rations that discovered fossils thought to be some of the earliest hominids (called Ardithecus ramidus, dated at about 4 million-plus years). Those same expeditions also led to the discovery of Australopithecus garhi, a 2.5-million-year-old homi- nid found in association with old bones with cut marks. Dr. Asfaw has held posi- 107

109 APPENdiX A Peter B. deMenocal is a professor at Lamont-Doherty Earth Observatory of Columbia University. He uses proxies in marine sediments, primarily stable isotope and trace metal geochemistry, to reconstruct past changes in ocean circu- lation and terrestrial climate. Recent research projects include Holocene climate and ocean circulation variability, tropical to extratropical paleoclimate linkages, Pliocene-Pleistocene evolution of tropical climates, and human evolution and past African climates. Dr. deMenocal is recognized as one of the leaders of the scientific effort to understand Earth parameters during the time that hominins evolved. He has a B.S. in geology from St. Lawrence University, an M.S. in oceanography from the University of Rhode Island, Graduate School of Ocean- ography, and a Ph.D. in geology from Columbia University. Andrew P. Hill is the J. Clayton Stephenson Professor of Anthropology at Yale University, and Curator of Anthropology in the Peabody Museum. Before coming to Yale in 1985, he held research positions at the National Museums of Kenya in Nairobi, and at Harvard. He is interested in the whole range of human evolution, particularly in the environmental and ecological context in which it occurred. Since 1968 he has carried out field work in eastern Africa, in Pakistan, and in the United Arab Emirates. For many years he has directed the Baringo Paleonto- logical Research Project, a multidisciplinary research program operating in the Tugen Hills, Kenya. He teaches courses on different aspects of human evolution, faunal analysis, and taphonomy. Dr. Hill has a B.Sc. (Honouurs) from Reading University and a Ph.D. from the University of London. Thomas C. Johnson is a Regents Professor of Geological Sciences at the Large Lakes Observatory and the Department of Geological Sciences at the University of Minnesota, Duluth. His research interests include paleoclimatology based on the analysis of lake sediment cores and sedimentological processes in large lakes, focusing mainly on those in the East African Rift Valley. Dr. Johnson was the founding director of the Large Lakes Observatory, and served as a member of the Great Lakes Research Managers Council of the International Joint Com- mission. He was the cofounder and served on the Steering Committee of the International Decade for East African Lakes (IDEAL) from 1995 to 2005.

111 APPENdiX A Alan C. Walker (NAS) is the Evan Pugh Professor of Anthropology and Biology at The Pennsylvania State University. Dr. Walker endeavors to extract ancient behaviors from the fossil and taphonomic record. Teeth record information about an individual’s life history and semicircular canals are tuned to a species’ rapidity of locomotion. Dr. Walker is now developing nondestructive methods for examin- ing tooth enamel and measuring fossil labyrinths so that rare hominoid and homi- nid specimens can be used. He is a research associate of the National Museum of Kenya and has had many collaborative field programs with the museum, the latest being at Allia Bay, east Lake Turkana. He has a B.A. (Honours) in geol- ogy from Cambridge University and a Ph.D. in anatomy and paleontology from the University of London. He also has an honorary D.Sc. from the University of Chicago. Dr. Walker is a Fellow of the Royal Society. National Research Council Staff David A. Feary is a Senior Program Officer with the NRC’s Board on Earth Sci- ences and Resources and staff director of BESR’s Committee on Seismology and Geodynamics. Prior to joining the NRC, he spent 15 years as a research scientist with the marine program at the Australian Geological Survey Organisation (now Geoscience Australia). During this time, he participated in numerous national and international research cruises to better understand the role of climate as a primary control on carbonate reef formation and to improve understanding of cool-water carbonate depositional processes and controls. He is a member of the Science Planning Committee of the Integrated Ocean Drilling Program. Dr. Feary received B.Sc. and M.Sc. (Honours) degrees from the University of Auckland and his Ph.D. from the Australian National University.
