With wide experience in Stone Age archaeology and hunter-gatherer studies, his first love is rock art.
As a founder member of the University of Cape Town’s Spatial Archaeological Research unit, he has participated in numerous surveys in the Western Cape and excavations of sites in the Cedarberg area, including Bushmans Kloof and Fallen Rock.
His 25- year career at UCT’s Archaeology Department spanned organizing student field work as well as teaching and publishing.
Subsequent work includes outreach programmes, community projects, consultative work around the protection and management of rock art sites – and helming an ongoing project locating and recording rock art sites in the Cedarberg where he is responsible for a database with nearly 2,000 sites to date in the Western Cape.
Having travelled widely and presented work at conferences both locally and in Europe and Australia, he is particularly interested in rock art of other parts of the world, while his specific interests are the combination of formal archaeological techniques with the study of rock art.
