Research Areas

  • Stable Isotope Geochemistry

Research Interests:
Stable isotope geochemistry; meteoric origin, fractionation mechanisms, and transport of ground waters. Chemical hydrology; chemical and isotopic interaction of water and rock in environmental, groundwater and hydrothermal circulation systems.

Recent Projects:
Stable isotope chemistry of surface and groundwaters in southern California; water-rock interactions in the Salton Sea geothermal system, California; fluid inclusions as indicators of chemical evolution of geo-fluids, water quality degradation and movement of nitrate in waste water.
