My research investigates the comparative anatomy of the skull in primates as it relates to human evolution. I employ 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.
