I am a palaeo-archaeologist with an expertise in lithic analysis. In general, I am interested in the period spanning the late Earlier and the Middle Stone Ages of sub-Saharan Africa (beginning ~400-30,000 years before present) and the forces that signal key shifts and increasing diversity in human behaviour during this period. Specifically, my primary area of interest relates to prehistoric landscape use, associated resource procurement strategies on the regional scale and what systems of stone tool production at specific localities can tell us about the relationships early populations had with their surroundings during the late Pleistocene of South Africa. Principle research objectives are to explore the symbiotic nature of raw material availability and selection, the range of lithic technologies employed, evidence for exploited subsistence resources and ancillary behavioural indicators including site spatial patterning.
In South Africa I am currently permit holder and director of excavations at the site of Uitspankraal 1 (UPK 1). UPK 1 is a large open-context Pleistocene river terrace located at the confluence of the Beidouw and Doring Rivers, Western Cape that demonstrates evidence for human occupation beginning in the Earlier Stone Age through to the Later Stone Age. The project is part of the larger Pleistocene Landscape Project (PLP) research programme coordinated by Dr. Alex Mackay of the University of Wollongong, Australia. Additionally, with William Archer of the Max Planck Institute of Evolutionary Anthropology in Liepzig, Germany, I co-direct excavations at Montagu Cave which is located in the Langeberg Range of the Western Cape. Collections amassed from previous excavations at Montagu Cave in 1919 and again between 1964-65, as well as recently renewed work at the cave, demonstrates evidence for large-scale stone tool production during the Earlier and Middle Stone Ages.
