The Department of Computer Science offers BA/BS, MS, and PhD degrees. Faculty research interests include: algorithms, computer systems, high performance computing, modeling and simulation, networks, programming languages and compilers, scientific computing, and security. The department maintains a state-of-the-art computing environment for experimental research and education.

At William and Mary students have the best of several worlds. Like a large research university, the faculty and their PhD students are actively engaged in research, with undergraduates and Masters students encouraged to participate. Like a small liberal arts college, the full-time faculty teach the courses from the freshman level to research seminars.
