I have been involved in FABI since my undergraduate studies where, as a mentorship student, I was bitten by the metaphorical bug and have not left since. I completed my undergraduate degree in Plant Pathology at the University of Pretoria, that for final year (2019), included doing a project to determine whether Lecanosticta species are causing needle blight disease on various Pinus species in Colombia. For my M.Sc., I am expanding on my previous study by investigating the spread and host diversity of Lecanosticta species in Colombia. Furthermore, I am also investigating the status of other pine needle diseases in Colombia to gain insight into the pathogens that may pose a risk to non-native pine plantations within the Southern Hemisphere. 

Other than uncovering these mysteries I enjoy hiking, reading and having a braai with family and friends.

Field trips



The FABIlous FABwarts School of Sci-craft and Wizardry

The meeting of the Epsilon Chapter of the Society for the Presentation of Outrageous Findings (SPOOF) hosted by FABI saw witches, wizards, elves, pixies, muggles, mudbloods and all other manner of magical folk and creatures join in the evening’s fun at the FABwarts School of Sci-craft and Wizardry.

Last tree planting event for 2020

Forty FABIans from the Tree Protection Co-operative Programme (TPCP) and Grain Research programme (GRP) got their hands dirty replanting 200 pine and 1500 Eucalyptus seedlings into potting bags at the last tree planting event for 2020 on 27 November. This year’s tree planting also included students from the GRP who harvested maize leaves.

FABIans’ excellence celebrated at UP Academic Achievers Awards

Eight FABI researchers were honoured at the University of Pretoria Academic Achievers Award event on 25 November. Professors Fanus Venter and Dave Berger were both honoured with the Exceptional Academic Achievers Award.
