I am a geochemist who focuses on measuring and evaluating the causes of sulfur isotope variations in Ocean Island Basalts (OIBs), Martian meteorites, pallasite meteorites, and a variety of lunar materials. The overall goal of my research is to understand how sulfur is processed on various solar system bodies by determining the dynamic interplay of volatiles with a planets' interior, surface, and atmosphere. Ultimately, I aim to use the detailed constraints of sulfur cycling on planets to identify the broad evolution of planets throughout their respective histories.
