Environmental Science and Engineering is a field within the Engineering Sciences area of study at the Harvard John A. Paulson School of Engineering and Applied Sciences. Prospective students apply through GSAS; in the online application, select “Engineering and Applied Sciences” as your program choice and select "PhD Engineering Sciences: Environmental Science and Engineering" in the Area of Study menu.
Human influence on the natural world’s ecosystems and resources has never been more prominent or problematic than it is today. In order to better understand and address environmental challenges, environmental scientists and engineers provide technical solutions and advance innovations in environmental measurements, modeling, and control through the application of scientific and engineering principles. Students in environmental science and engineering study the fundamental processes and technologies underlying environmental systems, including natural and polluted waters and soils, the atmosphere, climate, and energy. Students learn to apply these principles to develop solutions to complex environmental problems and to mitigate human impacts on the environment.
