African Arachnology. Various aspects of arachnid systematics and ecology are studied. The main focus is on the systematics and ecology of Afrotropical corinnid sac spiders, particularly ant-mimics in the subfamily Castianeirinae. This is one of the most poorly studied spider families in the region, and generic revisions presently underway indicate that the total diversity of this group is likely to increase at least five-fold. 

Other research areas include studies of spider biodiversity in habitats in the Free State Province, agroecosystems, and various conservancies. Biodiversity and ecological work focuses on the spider diversity of the Ndumo Game Reserve in Maputaland, KwaZulu-Natal, where more than 580 species of spiders have been recorded so far. Collaborative research includes studies on spider systematics and biology, particularly of termitophagous and myrmecophagous spiders, and karyology of South African arachnids.
