Research Profiles
I started out at FABI as a mentorship student in 2010, did my BSc(Hons) here in 2011, and then moved to Stellenbosch University. But being the fantastic place that it is, I had to come back! So after obtaining my PhD at Stellenbosch, I joined FABI as a Postdoctoral Fellow at the beginning of 2017. I still collaborate closely with my previous postgraduate advisors in Stellenbosch and continue to work in their laboratories.
I am excited about using genetic resources to survey populations and study adaptations, at both the population and individual levels. Whole-genome and transcriptome sequences are invaluable genetic resources that I use as “blueprints” in my research. These blueprints reveal aspects of the organism’s biology and ecology that can be further pursued by in vitro experiments. I find it particularly interesting to identify characteristics that enable organisms to invade and occupy specific niches. Especially when these can, subsequently, inform management protocols.
My postgraduate research considered the population genetics and genomics of ophiostomatoid fungi that occupy the flower heads of the iconic Cape Protea plants. Currently, my primary focus is on Teratosphaeria fungal pathogens of Eucalyptus trees in forestry plantations. The contrast between the closely related leaf and stem pathogens in the genus Teratosphaeria is specifically intriguing and is one of the focal points of my genomics-based research.

FABIans present at the Australasian Plant Pathology Society conference
The Australasian Plant Pathology Society (APPS) celebrated its 50th anniversary at their 22nd Biennial conference in Melbourne from 25-28 November. They met up with a number of FABIans at the meeting.
Modelling Workshop hosted by FABI
FABI hosted a simulation modelling workshop led by two leaders in the field, Dr Serge Savary and Dr Laetitia Willocquet; both senior scientists at the AGIR Research unit of INRA’s Research Centre of Toulouse in France.
