Overview

I am a biological anthropologist with scholarly interests in evolutionary and functional morphology and my research programs investigate a variety of questions about human and non-human primate evolution. In particular, I am interested in better understanding the evolution of primate locomotor behavior, and more specifically the evolution of human and non-human primate hand and foot function.
