I started off at Stellenbosch University and majored in Archaeology and Anthropology. I wanted to somehow incorporate both. I did a MSc in Botany, Nelson Mandela University, looking at indigenous plant use and the phenology of edible plants, in the south Cape, a very important area for research into modern human origins. I then did a PhD in Oceanography (biological), Nelson Mandela University, and studied the productivity and resilience of the intertidal zone on the south Cape coast for humans and the implications for human origins and cognitive modernity. My research is centered around human behavioural ecology and natural resource economies in various areas in South Africa. I also employ other disciplines to better understand the human subsistence relationships within ecosystems. I am also involved in the field of Ichnology.
