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 at the Florisbad Quaternary Research Department, National Museum. 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.
My first undergraduate degree (BS) was undertaken at Southern Methodist University (SMU, 1974) where I worked for Dr. Alan Skinner in the Archaeology Research Program and directed a number of CRM projects in Texas and New Mexico. I then read Archaeology for an BA degree at Cambridge under Dr. Charles McBurney and excavated with him at La Cotte de St. Brelade on Jersey. After graduating from Cambridge in 1976 I worked in Oklahoma for 3 years at the Museum of the Great Plains and I directed the nonprofit, Archaeological Research Associates, in Tulsa. My PhD degree was awarded at SMU in 1991, where I studied with Dr. Garth Sampson and worked on his Zeekoe Valley Archaeological Survey in South Africa. I then undertook excavations at Blydefontein Rock Shelter in South Africa for my dissertation research. While writing my dissertation I worked as a geoarchaeologist at Prewitt & Associates working on CRM projects throughout Texas. After finishing my PhD, I joined Mike Collins at TARL to co-direct the Wilson-Leonard project in Texas, and later spent 5 years at the Center for Archaeological Research, UTSA as the Assistant and Interim Directors. I joined the Texas State Anthropology Department in 1999 to establish the department’s first research center (CAS). I was promoted to a tenure-track Assistant Professor position in 2002, tenured as an Associated Professor in 2006, and promoted to full Professor in 2012.
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. Since 2009 I have served as Associate Dean for Research in the College of Liberal Arts.
