My active research interests include Stone Age archaeology of Sub-Saharan Africa, Paleoindian-Archaic and Southern Plains archaeology in the US, Hunter-gatherer foraging theory and Technological organization, Geoarchaeology, and Paleoenvironments.
Currently I am excavating Middle and Later Stone Age sites at Erfkroon and Baden-Baden in South Africa in collaboration with Dr. James Brink. The National Science Foundation, the Leakey Foundation, the National Museum and Texas State University have funded this research. I am also working with Garth Sampson to convert the NSF-funded Zeekoe Valley Survey data from South Africa into GIS format. The Bureau of Land Management has supported our field school excavations at Antelope Creek homesteads on the Cross Bar Ranch and NPS has funded research at the Alibates Quarries, both in the Texas Panhandle.
I co-chair the Anthropology Section for the Texas Academy of Science and I served as the 2011 President of the Texas Archeological Society. I am also Honorary Research Associate in the School of Geography, Archaeology and Environmental Studies at the University of the Witwatersrand in South Africa. I also serve as Associate Dean for Research in the College of Liberal Arts.
