My research spans deep geological, prehistoric, recent historical, and modern times, focusing on the behavior, evolution and geochemistry of vertebrate and invertebrate organisms. The unifying tool in my research is stable isotope biogeochemistry, which I use to address questions about past climate, environment, and ecology.
