About Dr. Wasiu O. Raji

My research focus on the application of geophysics to environmental, energy, and engineering problems with a broad range of topics which include earthed engineering infrastructures such as dams, tunnels, and roads; hydrocarbon and mineral exploration; groundwater development, pollution control, and remediation; and machine learning applications in geoscience. With about 15 years of university teaching experience, I have taught a broad range of subjects in geology and geophysics at the graduate and undergraduate levels in Africa, the United Kingdom, the United States of America, and Canada. I am currently associated with Carleton University, Ontario, Canada, and teaching Exploration Geophysics, Natural Disasters, Physics of the Earth, and Geoscience Data analysis.
