Mr. Unusiotame-Owolagba, Timothy Efe

Profile

I am an aquatic ecologist with expertise in phytoplankton and microalgae ecology. My research focuses on bio-physical interactions, light availability, primary production, water quality analysis, nutrient dynamics, stoichiometry, and the impacts of nutrient enrichment on microbial diversity, food webs, human health, and the environment. I also specialize in harmful algal blooms (HABs), including cyanobacterial blooms, studying their distribution, dynamics, and the occurrence of cyanotoxins and phycotoxins. Additional areas include algal ecophysiology, biogeochemical cycling, eDNA approaches, and human impacts on aquatic systems. My work integrates chemical, physical, and biological oceanography, biodiversity assessment, climate change effects, and sustainable use of water and land resources. I employ mathematical modeling of biological systems, ecological statistics, numerical ecology, and extensive experimental designs to test empirical ecological interactions.
