Terry Ritzman, PhD

Assistant Professor of Anatomy in Neuroscience


Dr. Ritzman is a biological anthropologist interested in the comparative anatomy of the skull in primates as it relates to human evolution. His research employs the comparative method and direct studies of fossil hominins to make inferences regarding the evolutionary processes that operated during the course of human evolution, as well as the patterns, documented by the fossil record, that were produced by these processes.
