Engineering and Applied Science

Director of undergraduate studies: Vincent Wilczynski, 238 DL, 432-4221,

Courses in Engineering and Applied Science fall into three categories: those intended primarily for students majoring in one of the several engineering and applied science disciplines; those designed for students majoring in subjects other than engineering, the applied sciences, and the natural sciences; and those designed to meet common interests of students majoring in engineering, the applied sciences, or the natural sciences.

In the first category, the departments of Biomedical Engineering, Chemical and Environmental Engineering, Computer Science, Electrical Engineering, and Mechanical Engineering and Materials Science offer courses intended primarily for majors in engineering and applied science disciplines. Courses in these departments may also be relevant for students with appropriate backgrounds who are majoring in chemistry, physics, biology, geology and geophysics, and mathematics. For information about majors in engineering and their related courses, see under Biomedical Engineering, Chemical Engineering, Computer Science, Electrical Engineering, Environmental Engineering, and Mechanical Engineering.

The School of Engineering and Applied Science is responsible for courses in the other two categories: technology for students majoring in subjects other than engineering, the applied sciences, and the natural sciences; and topics common to students majoring in engineering, the applied sciences, and the natural sciences. Courses for non–science majors are intended for all students seeking a broad perspective on issues of scientific and technological import, and they introduce students who may be planning careers in law, business, or public service to concepts and methods of engineering and applied science. Courses for science and engineering majors include topics in applied mathematics and computation.

* ENAS 430b / CENG 430b, Renewable Energy Technologies André Taylor

Using renewable energy technologies to address real-world energy problems in underdeveloped regions, with an international hands-on learning experience during spring break. Topics include: solar energy and battery technologies; how next generation solar cells and batteries are developed and characterized in the Yale Transformative Materials and Devices (TMD) Laboratory; how solar energy systems are installed commercially on Yale’s campus; and an overview of how government policies play a role in renewable energy technologies. Students prepare engineering simulations to tackle sample case studies of real world energy problems and exercise various problem-based practices to define and solve problems related to renewable energy. Class size is limited to six junior and senior undergraduate students. Permission by the instructor is required for registration.
