Research Interests

I specialize in aqueous and stable isotope geochemistry to interrogate the origins and history of geofluids in the crust, investigate fluid-flow in faults, and document fluid-rock-biosphere interactions. My research portfolio addresses basic and applied problems in continental tectonics, energy geosciences, and low-temperature geochemistry. My ongoing and future research directions directly align with community-identified “grand challenges” in tectonics. These include understanding the geochemistry and geochronology fluid-fault interactions, and how these influence societally impactful problems such CO2 sequestration and natural resource development. In addition to the theme of using isotopic systems as tracers of fluid-rock interaction, a common thread in my research portfolio is evaluating how the scale and extent of chemical and isotopic equilibrium impact interpretations of past fluid compositions and temperatures.
