Biography

Biography

Dr Deokary J. Matiya is a Lecturer in the Department of Biological Sciences at the Dar es Salaam University College of Education, University of Dar es Salaam. He holds a PhD in Applied Zoology, an MSc in Medical Parasitology and Entomology, and a BSc with Education, and specialises in biomedical sciences. His teaching areas include entomology and parasitology, vector and pest management, and developmental biology. His research focuses on the epidemiology, therapeutics and control of malaria, schistosomiasis and soil-transmitted helminths, as well as the biology, ecology and control of their vectors. He is also involved in biomedical research using Galleria mellonella (greater wax moth) as an experimental model, and his broader research interests include insect diversity and conservation, insect-based products for human and animal consumption, and the use of insects as bioindicators of environmental pollution.
