Currently my research focus is on the South African National Diatom Collection where I work to further broaden our understanding of the taxonomy of endemic diatom species. I am also involved in the training of MSc students on diatom ecology and taxonomy, as well as supervising of an MSc student. My research have mainly focussed on freshwater (rivers and wetlands) diatom ecology, ecotoxicology, paleoecology and taxonomy. My research mainly focuses on diatom ecology and ecotoxicology, with ecotoxicology at the centre of my research where I study the effects of different chemicals on diatom morphology and vitality.
