Dr. Henry B.O. Lung’ayia

Dr. Henry B.O. Lung’ayia is a Senior Lecturer in the Department of Biological Sciences (MMUST). He received his PhD in Sciences with specialization in Aquatic Ecology from Vrije Universiteit Brussel (Free University of Brussels, VUB) and MSc in Fundamental and Applied Marine Ecology also from VUB. His area of academic and research interest is in micro-algae mainly phytoplankton and diatoms on scope of biodiversity, as indicators of ecological water quality, fisheries production and algal toxins.

His major scholarly contribution was on phytoplankton structure and environmental relationships in Lake Victoria, and diatoms as indicators of water quality in inflowing rivers. He has also worked on fish biology and ecology; post-harvest loses of fish and fish products; cyanobacteria microcystin toxicity in Lake Victoria.

Some of his key published works include: -
