Prof Irene Barnes
Professor
About
I am a full Professor in the Department of Biochemistry, Genetics and Microbiology (BGM), at the University of Pretoria and a research leader in the Tree Protection Cooperative Program (TPCP), the Centre of Excellence in Plant Health Biotechnology (CPHB). I also lead the Kiwi Protection Program (KPP).
My research focuses mainly on the taxonomy, phylogenetics and population biology of fungal pathogens that affect forest trees - including Eucalyptus, Pinus and Acacia species. This work includes determining the biodiversity of fungi in plantations and describing new fungal species, tracing the infection pathways of some of the most serious forest pathogens through population genetic studies, and investigating pathogenicity and host specificity. Some of the fungi of particular interest to me include the pine needle pathogens and the vascular wilt and root rot pathogens.
I currently hold leadership positions in the African Mycological Society (AfriMa), the International Union of Forest Research Organizations (IUFRO) in the Division of Forest Health, and am on the executive council of the International Mycological Association (IMA).
