He has expertise in investigating animal responses to changes in feed, environmental and other physiological conditions. He also studies the role of climatic variables and its implications in feed-forage yield as well as the complex interactions of nutrient variability with associated climatic variables. An important aspect of his expertise involves data management and analysis. Prior to 2009, he was a Project Manager of the World Bank-assisted National Fadama Development Project (Imo State Fadama II Project) a poverty alleviation programme which was aimed at sustainably supporting farmers and rural folks through the provision of grants for productive agricultural enterprises as well as supporting the natural resource ecosystem in their areas through the Global Environmental Facility) GEF supported environmental management programme for the Fadama ecosystems within these areas.
