Research


Area(s) of Interest

My primary interest is the genetic interaction between plants and pathogens, more specifically cereals and their respective rust pathogens. The different aspects that I investigate are:

- The genetic interaction between wheat and stem rust in terms of genes involved in the adult plant resistance response.

- Genotyping cereal rusts, include wheat stem, leaf and stripe rust, sunflower rust and oats stem rust.

- The identification of naturalized Berberis species in South Africa.

- The identification of wheat viruses and their associated vectors in South Africa.

- The control of cereal urediniospore germination using natural compounds.
