Steve is a professor of anthropology at the University of Oregon. As a paleontologist and paleoanthropologist his interests are in human and primate evolution as well as ways to quantify biological shape and how it changes. He has conducted field and museum research in eastern Africa over the last 3 decades, which has primarily focused on the evolution of African monkeys and its relationship to climatic change. He is particularly interested in understanding what roles they played in their ecosystems, what those past ecosystems were like, and what larger aspects of Earth history and evolution they can help us to understand.
