Tim White is Director of the Human Evolution Research Center and Distinguished Chair in Life and Physical Sciences at Berkeley. He is a co-director of the Middle Awash research project in Ethiopia. His primary interests involve human evolution in all its dimensions. His research emphasizes fieldwork designed to acquire new data on early hominid skeletal biology, environmental context, and behavior. He has worked on hominids spanning the Pliocene and Pleistocene, from phylogenetic, functional, and ecological perspectives. He has investigated bone modification in a variety of archaeological and paleontological contexts. His ongoing research includes fieldwork in Ethiopia and Turkey, as well as laboratory studies and infrastructure development and training in these and other countries.  He is the author of several books, including Human Osteology, The Human Bone Manual, and Prehistoric Cannibalism at Mancos, and co-authored the new hominids Ardipithecus, Australopithecus afarensis, and Au. garhi.
