Research Summary

(inferred from publications by AI)

The researcher's work centers on advancing hydrological studies through innovative methodologies, particularly emphasizing the integration of AI and machine learning in groundwater characterization, forecasting, and analysis. They utilize geophysical tools such as aeromagnetic and electromagnetic datasets, along with remote sensing techniques like spectral time-domain induced polarization, to assess environmental impacts in Ghana's catchments and other regions. The researcher also integrates geophysics with gravity measurements and GIS technologies for comprehensive environmental evaluations. Their focus includes education, especially geography-related studies, addressing both historical and modern contextual influences in Ghana. The research explores broader environmental dynamics, such as coastal and marine interactions, while highlighting the importance of qualitative interpretations and time-domain analyses in understanding hydrological processes.
