 Qualifications:

PhD (Stellenbosch University)

 Research focus:

 My research focus is on fungal population genetics using molecular techniques. This includes research on genetic variation within as well as between species. Thus, a certain component of the work done in my group could also be considered to be molecular taxonomy. I also, however, have an interest in basic evolutionary biology based on ribosomal RNA-genes and this extends beyond fungi. I therefore have a variety of collaborations with research groups working on a spectrum of different organisms. Much of this collaboration is in association with the tree pathology research group and the emphasis of this research has therefore been on important plant and tree pathogens. As part of our effort to deal with tree diseases, I currently direct a programme aimed at detecting trait-linked markers in trees. This programme is supported by major players in South African Forestry.

Understanding the population diversity of a pathogen is an important aspect of being able to control the degree of disease and disease spread. The genetic diversity of a pathogen is not only determined by the genetic material in the fungal genome. Fungi also have extrachromosomal nucleic acid, the most common of which is dsRNA. In some fungi this dsRNA has been shown to be associated with hypovirulence. We are also investigating the presence of dsRNA in South Africa's more important tree pathogens with the view to using dsRNA as a means of biological control. Various breakthroughs have already been made on this front.
