Research Interests

My main specialty is computational geomechanics. I develop and apply massively parallel, multi-physics numerical models for a variety of subsurface processes with objectives in both enhancing energy recovery and minimizing environmental impacts. Applications include the stimulation of unconventional oil and gas reservoirs, engineered and hydrothermal geothermal systems, and CO2 sequestration. I am one of the original developers of LLNL’s GEOS code. I am also active in the study of geomaterials using particle-based simulations.
