ESE scientists and engineers address the fundamental physical, chemical, and biological processes that define Earth’s environment and provide the rigorous scientific and engineering underpinnings needed for rational public policy design. The department trains students to solve fundamental problems that cut across traditional disciplinary boundaries and acquire a broad base of knowledge of environmental systems covering Earth’s atmosphere, oceans, and biosphere. Students in ESE receive a broad education and carry out research addressing some of the grand science and engineering challenges of our times.
