RESEARCH AREAS
Petrogenesis of the Early Cretaceous Sierra Nevada batholith: field-based petrographic and geochemical investigations of the isotopically primitive, ultramafic to intermediate plutonic rocks exposed in the western Sierra Nevada foothills. Applications of environmental isotopes to groundwater studies: use of oxygen, hydrogen and tritium-helium isotopes, in conjunction with general minerals, to investigate recharge sources, subsurface flow paths and flow rates, and extent of water-rock interactions.
