Caleb Ojo is a PhD student at the College of Engineering, IT and Environment (CEITE) with Professor Bogdan Dlugogorski as his principal supervisor. He obtained a BSc in Industrial Chemistry and MSc in Analytical Chemistry from the University of Ibadan and another master’s degree in Environmental Science from the University of Aberdeen. He is interested in the chemistry of the environment which involves the origin and fate of pollutants and how these pollutants can be eliminated with low-cost methods. He is also researching waste valorisation via a circular economy. He derived toxicity thresholds for Cu and Zn in agricultural soils which can serve as soil guideline values. He has studied the use of clay and biomass as a means of water purification. Through kinetics and fate-modelling software, he monitors the mobility and bioavailability of pollutants in different environmental compartments. His research works are geared towards the generation of policies that would favour the populace and the environment. He has experience as a senior environmental scientist and meteorology officer in a leading firm in Nigeria. He is a recipient of various prestigious awards and his publications include the fate of polychlorinated biphenyls and pharmaceuticals.
