Research Profiles

I have been involved in FABI from my undergraduate studies, as a mentorship student, and from there my interest grew in the field of plant pathology and the impact genetic research can have on such studies. I completed my master's and PhD degrees in Genetics at FABI. My postgraduate studies focused on the host specificity of two Ceratocystis species, C. fimbriata occurring on sweet potato and C. manginecans occurring on various tree species. This included the development of a genetic linkage map and the identification of QTL markers associated with the aggressiveness of these fungal species to distinct hosts. Further genome comparisons of the two species were performed to identify genomic regions unique to each species, likely influencing their distinct host ranges.

I am currently a Postdoctoral fellow in the Macadamia Protection Programme, focusing my research on some of the pests and pathogens that are a major threat to these crops. I'm passionate about understanding the genetic foundation of various symbiotic interactions, between mutualist and their host as well as parasites and their host. Our goal is to use this knowledge to improve plant health and ensure future food security.

I love the outdoors and enjoy activities such as hiking, bird watching and jogging.

FABI researchers attend the International Macadamia R&D Conference in China

The annual International Macadamia R&D Conference was held in Lincang City, Yunnan, China from 5-9 November. Macadamia Protection Programme research leader Dr Gerda Fourie and FABI postdoctoral Fellow Dr Arista Fourie joined 300 delegates from 12 countries, consisting mostly of senior researchers, institute directors and consultants.

Fourteen FABIans capped at the 2019 Spring Graduation Ceremony

The University of Pretoria conferred 14 postgraduate degrees – eight PhD degrees and six MSc degrees – to FABIans during the Spring Graduation Ceremony on 5 September. Congratulations to these FABIans on their remarkable achievements!
