I am an entomologist with an interest in the systematics and biogeography of dung beetles and related scarab beetles. I am cataloguing and describing the impressive biodiversity of Afrotropical dung beetles to address broader evolutionary questions, such as the role of geological uplift and climatic changes in the late Cenozoic in the diversification and possible extinction of scarab beetles. Currently, I hold a research appointment as Principal Museum Scientist at the National Museum, Bloemfontein, South Africa.
