I have been recognized for my research in the area of Earth Systems History and paleoceanography which has earned me a leadership role in the paleoclimate community. My research has led to a better understanding of the history of global change. Within the University community, I have worked hard to develop strong links between the Department of Earth, Environmental and Planetary Sciences and Environmental Studies, the Institute at Brown for Environment and Society, and Ecology and Evolutionary Biology groups. I teach broad-reaching courses such as "Earth: Evolution of a Habitable Planet", "Ocean Biogeochemistry", and "The Enigma of Warm Climates in the Geological Record."
