The School of Engineering and Applied Science spans a number of buildings at the eastern edge of campus.
The Engineering Quadrangle, or EQuad, is home to four of six departments: Chemical and Biological Engineering; Civil and Environmental Engineering; Electrical Engineering; and Mechanical and Aerospace Engineering. The Department of Computer Science is across Olden Street in its own building. The Department of Operations Research and Financial Engineering is nearby in Sherrerd Hall.
Hoyt Lab on William Street provides laboratory space for biological engineering. The Princeton Institute for the Science and Technology of Materials is located in Bowen Hall. The Andlinger Center for Energy and the Environment occupies a major new building, completed in late 2015, at the intersection of Olden Street and Prospect Avenue.
