Bio

My research interests lies in the integration of gravity, magnetic, and geologic methods towards the study of Precambrian basements, basins, and rifts of continental interiors. I have been using satellite and ground based gravity, airborne magnetic data as well as shuttle radar tomographic mission to understand the kinematics of pre-rift structures and their influence in rift initiation and propagation. In particular, I am examining the role of pre-rift structures on rift formation, a subject of much interest among geoscientists in the search for conventional hydrocarbon reservoirs. Currently I have a running collaborative project-Dry Rifting in the Albertine-Rhino Graben (DRIAR) funded by the National Science Foundation (NSF). We are combining geophysical, geodynamic modeling and geological data to unravel the process responsible for the initiation of the Magma poor Albertine of western branch of the East African Rift System.

My energy is also focused towards near-surface geophysics, particularly in the application of seismic, geo-electrical methods (electrical resistivity, induced polarization, self-potential, electromagnetic induction, and ground penetrating radar) to groundwater contamination, engineering, agriculture, and environmental problems. On a global community participation, I am interested in investigating geophysical signatures left behind in former nuclear test sites. Such studies are important and will form the foundation for the development of more robust geophysical models necessary for the characterization of nuclear tests if conducted by any state.
