Research Interests

My work at LLNL focuses on the application of high performance computing (HPC) on geomechanical processes involved in unconventional reservoir stimulation and production. Applications include the development and evaluation of stimulation and production strategies for engineered geothermal systems (EGS), as well as stimulation optimization for unconventional oil and gas reservoirs. I am one of the original developers of LLNL's GEOS code. Also active in the study of geomaterials using particle-based simulations.
