Research Interests

Professor Oware’s research interest is in the application of geophysical techniques, such as electrical resistivity (ER), thermal, and ground penetrating radar (GPR) to non-invasively characterize aquifer heterogeneities and subsurface processes within a geostatistical inverse modeling framework. His major research objectives are in the development of innovative inverse modeling strategies for enhanced imaging of fractured rock aquifer/reservoir properties and improved monitoring of subsurface flow and transport processes, through numerical, lab, and field-scale experiments.
