My research applies stable-, radiogenic isotope and trace element geochemistry in mineral chemistry and metamorphic petrology. Our specific focus in this realm is on documentation of ancient protoliths and to unlocking records of atmosphere-ocean-crust interactions over geologic time. Our work also explores numerical and analytical modeling of planet formation, the thermal affects of accretion, and how records of these processes are contained in minerals. Finally, we apply this knowledge to understanding the origin of the biosphere on cosmochemically Earth-like planets.
