I am a limnologist and Senior Lecturer at the Obafemi Awolowo University, Ile-Ife, Nigeria. I have had the privilege of attending some some professional training courses in conservation in the UK, USA and the Netherlands; hence, my research interests focus on freshwater ecosystem conservation. Specifically, I investigate the conservation values of freshwater systems using the macroinvertebrate index approach. I also conduct research on freshwater ecotoxicology with respect to heavy metals and other toxicants. I have also been a visiting researcher at the German Federal Institute of Hydrology where I conducted a research on the occurrence of microplastics in some freshwater invertebrates from Nigeria.
