Daniel Lieberman is the Edwin M Lerner II Professor of Biological Science and Chair of the Department of Human Evolutionary Biology at Harvard University. He received his A.B from Harvard in 1986 (Summa cum laude), an M.Phil from Cambridge University in 1987, and a Ph.D. from Harvard in 1993. His research is on how and why the human body is the way it is, with particular foci on the origins of bipedalism, how humans became such superlative endurance runners, and the evolution of the highly unusual human head. To address these questions, he combines experimental biomechanics, physiology, paleontology, and comparative anatomy. Lieberman teaches courses on human evolution, anatomy, and physiology. He has published more than 100 peer-review papers and his two most recent books are The Evolution of the Human Head (Harvard University Press, 2011) and The Story of the Human Body (Pantheon Press, 2013).
