Biography
Richard Bribiescas is Professor of Anthropology and Chair of the Anthropology Department. He is also Director of the Yale Reproductive Ecology Laboratory and the Program in Reproductive Ecology, a YIBSsponsored research initiative. His most notable research involves the evolutionary biology and endocrinology of human and comparative life histories, reproduction, aging, and metabolism. He has conducted field research among the Ache of Paraguay as well as populations in Venezuela, Japan, Ecuador, and the United States as well as various species of non-human primates. He is presently collaborating with Professors Larry Sugiyamaand Josh Snodgrass of the Department of Anthropology at the University of Oregon, as well as Professor Felicia Madimenos of the Department of Anthropology at Queen’s College CUNY on the Shuar Health and Life History Project in Ecuador.
Bribiescas received his B.A. in Anthropology and Psychology (double major) from the University of California, Los Angeles, afterwards earning an A.M. and Ph.D. in Anthropology from Harvard University. Prior to his position at Yale, he was a Post-Doctoral Research Fellow in the Reproductive Endocrine Unit of Massachusetts General Hospital in Boston. He is author of Men: Evolutionary and Life History (Harvard University Press, 2006), a comprehensive examination of the evolutionary biology of human males which was awarded the 2007 Bronze Medal in the category of science by the Independent Book Publishers Association. In 2007 he was also awarded the Medal of 600 Years Anniversary of the Restoration of the Krakow Academy by Jagiellonian University, Krakow, Poland, for his research in human reproductive ecology.
Professor Bribiescas serves on the editorial board of the American Journal of Human Biology, Evolution, Medicine, and Public Health, and the Annual Review of Anthropology. Current courses taught by Professor Bribiescas include Human Evolutionary Biology and Life History, as well as graduate seminars in behavioral endocrinology, reproductive ecology, aging, and life history theory.
