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 examining tooth enamel and measuring fossil labyrinths so that rare hominoid and hominid 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 geology 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.

David A. Feary is a Senior Program Officer with the NRC’s Board on Earth Sciences 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.
