Research focus

One of the central focal points of my research is to understand the interplay between species diversity and historical time in southern Africa. In this respect I have focused on evolutionary relationships of a wide number of terrestrial and inland aquatic groups, primarily invertebrates. In this respect I am currently investigating the systematics of South African velvet worms and a revision of the Afrotropical freshwater crab fauna based on DNA sequence data and morphology. I have also in recent years worked extensively on limbless skinks and have recently initiated a large-scale project on tortoises. The main objectives of all these studies are to better understand and document the spectacular biological diversity of South Africa to aid the conservation of these groups.
