My primary research objective is the discovery, description, and analysis of new fossil primates —especially human ancestors, or hominins— from eastern Africa. I am an Associate Curator and Chair of Anthropology at the American Museum of Natural History (AMNH), an Associate Professor in the museum’s Richard Gilder Graduate School, and primary faculty in the New York Consortium of Evolutionary Primatology (NYCEP). I am significantly involved in AMNH Anthropology collections acquisitions, research, repatriation, and stewardship, among other museum-related activities.
