Research Profiles

Primary Supervisor
Godfrey Kgatle

I am a mycologist specialised in the taxonomy of Aspergillus, Penicillium, Talaromyces and other moulds from the natural and built environment. My research focus includes their biodiversity, ecology, phylogenetics, nomenclature and identification with a particular interest in taxonomically robust ecological and biodiversity studies. My work has a strong field-work component and I do a lot of fungal isolations from various habitats, including extreme fungi. My major contribution to the international mycological community has been the accepted species lists for Aspergillus, Penicillium and Talaromyces that was published in Samson et al (2014), Visagie et al (2014) and Yilmaz et al (2014). Before these papers, describing new species in these genera was very complicated because of unavailable reference data. Since publishing these accepted species lists and associated DNA sequence reference data, Aspergillus grew from 339 to 413 species, Penicillium from 354 to 439 species, and Talaromyces from 88 to 145 species. These papers had a big international impact and has been cited a combined 786 times (on 2019/05/05). Accepted species lists are kept up to date on the International Commission of Penicillium & Aspergillus website.

My goal as a mycologist is to create a system of classification that is useful and make identifications easier. I remain focused on this for especially Aspergillus, Penicillium and Talaromyces by discovering and describing diversity, keeping their nomenclature updated, whilst curating, expanding and exploiting DNA databases for a wide range of downstream applications. In addition to this, my research is expanding into the food and feed security sector where mycotoxigenic fungi is one of the most important risks.
