      Research 

My research interest revolves around the field of Engineering Geology, Hydrogeology and Environmental Geology. The application of geologic knowledge to practical problems is the focus of the fields of engineering, hydro and environmental Geology. Engineering geology is the application of Geology and related disciplines to the understanding and solution of earthwork or geotechnical problems. Hydrogeology on the other hand deals with the assessment of groundwater systems with emphasis on the occurrence, distribution, hydraulic movement and chemistry/quality while Environmental Geology involves the protection of human health and safety through understanding geological processes. For example, it is critically important to understand the geology of areas where people propose to store nuclear waste products.

Currently, my research work includes the evaluation of locations for landfill site in the crystalline Basement complex and sedimentary terrains of Nigeria with particular emphasis on the application of geophysics for characterization of subsurface horizon and understanding the groundwater occurrence, application of geochemistry and mineralogy to characterize underlying soils and provide information on other properties that can prevent or promote contamination of groundwater by leachate from waste. Furthermore the geotechnical properties of waste soil from open dumping area including the reaction between leachates and soil types and the permeability characteristics of soils are being investigated.

Other areas of interest include foundation investigation for structures, soil improvement and stabilization, characterization of geomaterials for the understanding and solution of earthwork problems to achieve sustainable development. Furthermore the characterization of groundwater systems of the Basement Complex terrain is under investigation.
