I am a biological anthropologist who studies human evolution. My main research interests include the study of hominin (humans and the extinct relatives) taxonomy and phylogeny using cranial morphology, the application of geometric morphometrics to study skeletal variation and functional morphology, and the evolutionary history of Plio-Pleistocene Homo.
I am currently an Associate Professor in the Department of Anatomy at Midwestern University in Glendale, AZ. After earning my Ph.D. in anthropology at the City University of New York (part of the New York Consortium in Evolutionary Primatology) in 2007, I was a Research Instructor in the Department of Anatomical Sciences at Stony Brook University and then an Assistant Professor in the Department of Anthropology at the same university.
