My research interests encompass a broad spectrum of geochemistry, including stable isotope geochemistry, volatile cycling, metamorphism and volatile transport in subduction zones, serpentinization, and fluid-rock interactions and metasomatism in the high-T environment. Most of my research involves using stable isotopes as a geochemical tracer of fluids in various tectonic and geologic settings from the upper mantle, the oceanic lithosphere, the plate interface, forearc thermal springs, and arc volcanoes. However, I have been involved in a wide range of research including, the isotopic composition of lunar samples and hyperarid soils.

I oversee one of the stable isotope labs in the Jackson School of Geosciences which houses a ThermoElectron MAT 253, silicate laser extraction line, chlorine purification line, and TC/EA. The lab has the capabilities for oxygen, hydrogen, chlorine, nitrogen, carbon, and sulfur analyses in silicates (terrestrial and extraterrestrial), atmospheric and volcanic gases, carbonates, fluid inclusions, water, and phosphates.

My research is focused on understanding the evolution of Mediterranean-style subduction zones with constraints from exhumed subduction complexes at the Betic Cordillera (Southern Spain) and Sikinos and Ios islands (Cyclades, Greece). My approach is to integrate a suite of geochronologic and geochemical analyses on zircon, apatite, and rutile, including U-Pb and trace elements split-stream analyses as well as 2D elemental...

My research incorporates stable isotope geochemistry, reactive transport modeling, field work, and hydrology to understand the geologic carbon cycle. Whether deep in the crust or at the Earth's surface, I see the physics and chemistry of fluid-rock interactions as a unifying lens to probe whole-Earth geochemical cycles. I have worked on several projects related to skarn formation, namely on how...
