Research Profiles

After her four-years studying the humanities (BA Honours in Anthropology), Dr van der Nest turned her attention to the biological sciences. She obtained her BSc from UNISA, and MSc in Industrial Biotechnology from Newcastle University in the United Kingdom. After obtaining a PhD in Genetics from the University of Pretoria, she embarked on a two-year postdoctoral study in Sweden at the Swedish University of Agricultural Sciences in Uppsala. She then returned to South Africa for a research fellowship at Forestry and Agricultural Biotechnology Institute (FABI), and later worked as Senior Researcher in Bioinformatics at the Biotechnology Platform on the Onderstepoort campus of the Agricultural Research Council (ARC). During her time at the ARC, Dr van der Nest was also an Extraordinary Lecturer in the Department of Biochemistry, Genetics and Microbiology at the University of Pretoria. Most recently she returned to FABI where she joined the Avocado Research Programme (ARP). Her research now focuses on the use of genomics to study the biology, ecology and evolution of fungi, especially Rosellinia necatrix.
