Zennah Kosgey, a Kenyan Research Scientist at the Kenya Agricultural and Livestock Research Organization (KALRO)-Food Crops Research Centre in Njoro, is at the forefront of disease surveillance in wheat-growing regions of Kenya. She leads efforts in race typing and characterization of stem rust and yellow rust isolates, as well as conducting efficacy tests for new fungicides. Her impactful contributions transcend national boundaries. Serving as the KALRO lead on the Plant Health Initiative (PHI), in collaboration with CIMMYT, she has been instrumental in the evaluation and screening of rust resistance monitoring nurseries. Her work significantly contributes to assessing virulence diversity and shifts in new virulence working closely with the global rust reference centres. Zennah holds a Ph.D. from the University of Minnesota in the USA, under the guidance of Prof. Ruth Dill-Macky and Dr. Mathew Rouse. She earned her M.Sc. in Plant Breeding from Egerton University in Kenya and her B.Sc. in General Science (Botany & Zoology) from Moi University in Kenya.
