Dr. Dennis M.W. Ochieno

Dr. Dennis M.W. Ochieno is a Senior Lecturer and Researcher in the Department of Biological Sciences. He holds a Doctorate degree in Production Ecology & Resource Conservation, Master of Science in Agricultural Entomology, and Bachelor of Education (Science) in Botany & Zoology. His research and teaching interests are in Multitrophic Interactions between microorganisms, plants, plant-parasitic nematodes, insects and various biotic and abiotic factors, focusing on the phyllosphere, rhizosphere and the endophytic niches, and how these are influenced by various Integrated Pest Management (IPM) technologies.

Some of his key published works include: -
