This exceptional woman, a finalist (see end of article)* in this year’s Department of Science, Technology and Innovation’s (DSTI) South African Women in Science Awards (SAWISA) is a Full Professor in the Department of Biochemistry, Genetics and Microbiology at the University of Pretoria (UP).
She obtained her PhD in Plant Pathology in 2007 from Dundee University in Scotland. Her academic journey began in 2008 at the University of Johannesburg (UJ) and in 2009, she joined the UP as a Senior Lecturer where she currently is Associate Professor in the Department of Biochemistry, Genetics and Microbiology. She was promoted to Associate Professor in 2015 and Full Professor in 2022.
Lauded by the DSTI, she is a 2025 finalist for the prestigious SAWISA award for excellence, leadership and transformative impact in research and innovation in Natural and Engineering Sciences. SAWISA celebrates the outstanding contributions of women researchers across disciplines, inspiring future generations and advancing equity in science, technology, and innovation.

Prof Moleleki’s research focuses on potato-pathogen interactions. It focusses particularly on understanding molecular virulence mechanisms of plant pathogens and how these interact with their hosts and one another. Her work contributes significantly to plant disease management and food security.
She has an impressive supervision and mentorship record – having mentored five postdoctoral fellows and supervised 10 PhD and 16 master’s students. She currently supervises four postdoctoral fellows and several PhD and master’s students. To date, she has published more than 50 peer-reviewed journal articles and five book chapters. Her research impact is evidenced by an h-index of 28 (Google Scholar), over 3 000 citations and a Field-Weighted Citation Impact score of 1, 75. A score of 1.0 is the global average. Any score above 1.0 is indicates greater citation impact. (For example, a score of 1.44 means publications are cited 44% more often than expected for their field and age.)
She has presented her work at global conferences, giving keynote addresses and has co-authored review articles and book chapters with leading scientists from different countries. These collaborations demonstrate the global relevance and interdisciplinary reach of her work. Prof Moleleki also serves on the editorial boards of several leading journals, including mSystems, Frontiers in Plant Science and BioMed Central Microbiology.
In 2024, she served on the Local Organising Committee of the 19th International Society for Microbial Ecology as session chair and convenor. In 2018, she served on the Scientific Committee for the International Congress of Plant Pathology. In the regional context, she has played an active role in advancing plant pathology and microbiology. She currently serves as a Council Member of the Southern African Society for Microbiology. In addition, she is a Fellow of the Pan African Scientific Research Council, where she serves on the executive committee.
Prof Moleleki has been recognised for her contributions to research and capacity building. In 2015, she was a finalist for the prestigious TW Kambule-NSTF Award in the Emerging Researcher category.
