Background:
I am a doctoral candidate in the paleoanthropology concentration at the University of Iowa. I received my BA at Texas A&M University in 2003, and my MA from the University of Iowa in 2006. My research focuses primarily on craniofacial evolution within the genus Homo during the Middle and Late Pleistocene. My dissertation research explores the evolutionary significance of the infraorbital region, and its utility in determining phylogenetic relationships in the hominin fossil record. I am also collaborating with fellow UI researchers on experimental research employing suture fixation in Sus scrofa to model evolutionary changes in human infraorbital morphology, and additionally, working on an osteological description of a previously unidentified hypochondroplastic dwarf skeleton, and an allometric re-examination of the reported 128,000 year old H. sapiens premolar (PU-198) from East Java, Indonesia.
