I am a computational geoscientist and subsurface engineer, with a strong interest in understanding, characterizing, and predicting subsurface flow and transport processes to optimize the development of underground energy, hydrological, and environmental resources. The research in my lab, Subsurface Enegry and Environmental Systems (SEES) Lab, integrates advanced computational and mathematical tools with the physics of multiphase flow in porous media to solve energy and environmental problems in geosciences. Examples of energy and environmental applications that we study include conventional and unconventional hydrocarbon reservoirs, enhanced geothermal systems, groundwater aquifers, and geologic CO2 storage systems.
