Research

My research aims to: 1) advance our fundamental understanding of fluid flow and transport processes in porous materials at microscale (i.e., pore scale) by developing computational models that explicitly represent the pore structures and the physical and chemical processes, and 2) then take the microscale understanding and develop predictive computational models at field scale (often involves model reduction via upscaling or multiscale formulations) to address practical engineering problems for energy and environmental systems in the subsurface including contaminant transport in soil and groundwater especially emerging contaminants such as PFAS, shale gas/oil production, and geological CO₂ storage.
