TheBiogeoscience Programis a community of students, postdocs, and faculty whose research interests converge at the boundaries of traditional natural science disciplines. The program emphasizes interdisciplinary research and coursework, focusing on the biogeochemistry and biogeophysics of natural and managed ecosystems, with faculty and students drawn from the departments of biologyand earth & environment. Research and curricular themes include the role of energy, mass and nutrient cycles in biosphere-atmosphere interactions, coastal processes, ecohydrology, climate change, regional-to-global environmental change, coupled human-natural systems, and sustainability science. The program is centered on graduate student training and is specifically designed for students wishing to pursue interdisciplinary research in topics spanning more than one discipline.
