Research interests include:
– Understanding the origin of life from the perspective of meteorites, metabolism, and phosphorus. Determining potentially prebiotic pathways leading to the origin of life using phosphorus redox cosmobiogeochemistry.
– Cosmochemical studies of planetary systems as constrained by thermodynamic equilibrium models. Cosmochemistry of meteorites and placing constraints on the impact history of the inner solar system.
– Constraining redox processes in the modern phosphorus biogeochemical cycle, including the role of lightning and meteoritic impacts.
