    I am interested in understanding, characterizing, and predicting subsurface flow and transport processes with the goal of enhancing our ability to effectively develop underground energy, hydrological, and environmental resources. Research in my group 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 hydrocarbon and geothermal energy recovery, groundwater flow and transport, and geologic CO2 storage systems.
