Through the Graduate School of Arts and Sciences, prospective students apply for doctoral and master’s degree study at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS). These programs lie at the interfaces of engineering, the applied sciences (from biology to physics), and technology. Graduate students work toward a degree in one of seven subjects—Applied Mathematics, Applied Physics, Computational Science & Engineering, Computer Science, Data Science, Design Engineering*, and Engineering Sciences, which includes bioengineering, electrical engineering, environmental science and engineering, and materials science & mechanical engineering. SEAS also offers an MS/MBA: Engineering Sciences program** jointly with Harvard Business School. PhD, SM, and ME students are enrolled in and receive their degree from the Graduate School of Arts and Sciences, even though they ordinarily study primarily with SEAS faculty.

SEAS faculty members, nearly 30 percent of whom have joint appointments in other research areas, have close ties with the science departments (especially physics, the biological sciences, chemistry, and Earth and planetary sciences) in the Faculty of Arts and Sciences and with Harvard’s professional schools (including Harvard Business School, Harvard Law School, Harvard Medical School, and Harvard Kennedy School). Programs that include work in one or more science departments are common. Students may pursue collaborative options through the Medical Engineering and Medical Physics (MEMP) program, which is part of the Harvard-MIT Division of Health Sciences and Technology (HST), and supplement their studies by cross-registering in other Harvard graduate schools or at MIT.
