The Environmental Engineering Program at Yale University emphasizes a multidisciplinary approach to solving environmental problems.Graduate students may pursue their educational and research interests across departmental lines and draw upon the resources of other departments and schools at Yale. Research and teaching in the program focus on fundamental understanding of the basic chemical, physical, and biological processes underlying environmental engineering and science problems.Areas of research specialization include: physical and chemical processes for water quality control, aquatic and environmental chemistry, transport and fate of chemical substances in the environment, assessing benign alternative chemicals and materials, environmental engineering microbiology, green engineering and product design, environmental nanotechnology, chemical aspects of wastewater reuse, membrane processes for desalination and water reuse, biological processes for water and energy production, aerosol science and technology, incineration of toxic wastes, industrial ecology, water and sanitation in developing countries, and links between public health, engineering, and sustainability.The relatively small size of the graduate programs at Yale facilitates very close interaction between students and faculty. Programs of study and research are arranged individually by each student in consultation with a faculty adviser.
