RESEARCH EXPERIENCE

LAWRENCE BERKELEY NATIONAL LABORATORY, Earth Sciences Division, Berkeley, CA.  Geological Research Scientist. 

Research on the thermodynamics, transport, and chemistry of aqueous systems in the subsurface, including research on the thermodynamics of gas hydrates, gas production from methane hydrate systems, the coupling of methane hydrates and global climate, carbon sequestration via subsurface CO2 injection, data reduction and uncertainty propagation using statistical methods, and “tight gas” simulation and engineering. Built and maintain online tools for physical property estimation and numerical simulation. 2004 to present.

SANDIA NATIONAL LABORATORIES, Combustion Research Facility, Livermore, CA. Technical Staff. 

Research on uncertainty quantification and its application to chemical systems modeling and complex reacting flow. Development of MPI-based parallel reacting-flow codes and development of statistical/Monte Carlo uncertainty quantification methods and software. 2001-2004.

MASSACHUSETTS INSTITUTE OF TECHNOLOGY, Research Assistant. 

Research on the molecular simulation and thermodynamics of supercritical water solutions. 1995-2000.
