We study the physics and mathematics of geophysical fluid flow in subsurface environments. We create theoretical and computational tools, including machine learning and artificial intelligence tools, to investigate these multi-physics processes and address engineering challenges related to energy and the environment such as geologic carbon storage, induced seismicity, hydraulic fracturing, groundwater remediation, and enhanced oil recovery. Our work is at the intersection of petroleum engineering, geophysics, hydrogeology, and computational mechanics. At USC, we are affiliated with the Mork Family Department of Chemical Engineering and Materials Science and the Sonny Astani Department of Civil and Environmental Engineering.
