He is a functional morphologist, specializing in the locomotion of early apes (hominoids) and human ancestors (hominins). He has a particular expertise in the foot and ankle and has worked most recently on the amazing ~2 million year-old skeletons of the South African hominin Australopithecus sediba. He has studied fossils in museums throughout East and South Africa. Additionally, he has studied locomotion in wild chimpanzees in Western Uganda, and currently oversees a research project studying the range of variation in modern human walking. Before entering academia, Jeremy worked as an educator at the Boston Museum of Science and continues to be passionate about science education. When he is not studying fossil foot bones, or lecturing on human evolution, Jeremy and his wife, Erin, are quite busy with their 3 year-old twin toddlers, Benjamin and Josephine. Guest Jeremy DeSilva
