Anna J. RagniI am postdoctoral researcher at the Institute of Human Origins at Arizona State University. I earned my PhD in Comparative Biology at the Richard Gilder Graduate School at the American Museum of Natural History where I studied locomotor ontogeny and postcranial functional morphology in primates. After earning my degree, I was a Peter Buck Postdoctoral Fellow at the Smithsonian National Museum of Natural History and an NSF Postdoctoral Fellow at California State University, Los Angeles. My graduate and early postdoctoral work used microComputed Tomography and geometric morphometrics to quantify how primate and mammal bones change through development in relation to locomotion, life history, and environment. My later research focused on creating a biomechanical model of the ~3.2-million-year-old “Lucy” skeleton to simulate its locomotor capabilities and better understand the evolution of fossil hominin locomotion. My current research explores the cranial anatomy of ~3.8-million-year-old Australopithecus anamensis.
