Vegetable pest entomologist
I am an entomologist, specializing in vegetable pests. My current projects include the potential of
Tuta absoluta as a potato pests, and investigations into control strategies of the potato leafminer.
Research focus: Potato virology, Molecular identification and characterization of viral bacterial and fungal pathogens of root and tuber crops
Research focus: Characterisation and identification of fungal phytopathogens of vegetables, medicinal and ornamental plants.
I am a plant pathologist specializing in Mycology. My current research interests include the characterisation and identification of fungal phytopathogens of vegetables, medicinal and ornamental plants. My research on soil-borne pathogens includes diseases on potato (potato rhizostonasis and
Fusarium wilt of sweet potato. My research on foliar diseases mainly focused on Alternaria, such as early blight of potato and
Alternaria blight of sweet potato
, but more in general on carrot, tomato, onion, Swiss chard and African leafy vegetables. I’m also involved with investigations of mycoflora of cowpea seed and medicinal plant products.

Research focus: Bacterial and fungal diseases of vegetables
I am a plant pathologist specializing in bacteriology. My current research interests include the investigation of bacterial wilt of potatoes and scab diseases of potatoes caused by Streptomyces species. Other projects include the discovery of PGPR on sweet potato and investigation of fungal leaf diseases of potatoes.
Research focus: Plant parasitic nematodes in crop production
I am a plant nematologist involved in potato, sweet potato, African Leafy Vegetables, medicinal plants, etc. The research interests are on screening for nematode resistance and developing integrated nematode management strategies for sustainable potato and sweet potato production.
Research focus: Identification and genetic characterization of viruses of vegetables
I am a plant virologist involved in
potato and sweet potato virus research, and the diagnostic of viruses of vegetables and ornamentals. The research interests are on the genetic characterization, diagnostics and technology transfer. The work contribute to the development of management strategies to control and minimize the spread of viral diseases.
