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 settings. However, I have been involved in a wide range of research including, the isotopic composition of lunar samples and hyperarid soils.

I oversee the High Temperature Stable Isotope Lab 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.

Graduate Students

Emily Hernandez Goldstein, Ph.D., expected 2017 (Committee Member)
I am currently pursuing my PhD under the supervision of Daniel Stockli. My research combines geochemistry, mineralogy and plate tectonics to better understand how minerals form, water-rock interactions, and the thermal and temporal evolution of ocean-continent transitions. I am developing a method that uses magnetite to date serpentinites in order to better understand how continents break up to form oceans. My research interests broadly involve novel geo/thermochronology techniques with applications to tectonics.

Edward W Marshall, Ph.D., expected 2017 (Co-supervisor)
My current research project looks at mantle hydration and metastomatism underneath the Colorado Plateau. My research will look into the timing and circumstances of the alteration as well as the rheologic implications on the stable Colorado Plateau. Prior research has been in the petrology and geochemistry of the Allsaw Anorthosite in the Ontario Grenville province, oxygen fugacity of the upper zone of the Bushveld Complex and the serpentinites of the Philadelphia area.
