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. The focus of my MSc project was to identify genetic markers that can be used to distinguish between closely related Ceratocystis species. This could then assist in studies investigating the spread and host diversity of species in the Ceratocystis genus.
For my PhD I 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 love the outdoors and enjoy activities such as hiking, bird watching and jogging.
