Curriculum Vitae
Current/Recent Research
1. Groundwater Protection and Management: Developing a framework for delineating and implementing groundwater source protection zones within Nigeria's crystalline basement terrains to improve sustainable groundwater resource management.
2. Environmental Geophysics: Investigating the dynamics and environmental impacts of naturally occurring bitumen contamination on soil and groundwater systems in the eastern Dahomey Basin, Southwestern Nigeria, using integrated geophysical and hydrogeological approaches.
3. Groundwater Exploration Using GIS and Remote Sensing: Generating groundwater potential maps for major urban centres through the integration of remote sensing, GIS, and geophysical datasets to support water resources planning and development.
4. Geophysical Applications in Precision Agriculture: Exploring the use of geophysical proxies for mapping soil nutrient distribution to enhance agricultural productivity and sustainable land management.
5. Groundwater Quality Assessment: Assessing and mapping groundwater quality in urban and rural communities around Osogbo and other parts of Southwestern Nigeria through hydrogeochemical characterization, water quality indices, and multivariate statistical analyses.
6. Climate and Environmental Risk Mapping: Applying remote sensing and GIS techniques to evaluate drought resilience and flood risk zones for improved environmental planning and disaster risk reduction in Southwestern Nigeria.
