For students in COS, the world is their playground. In general students end up in programs with a strong interdisciplinary, multi-disciplinary or trans-disciplinary component. Students go into academics - either directly or through postdocs, government, and industry. In industry, graduated students often work in firms with a strong research and development component, and often engage in research. In academia, all fields are open - from the social sciences to computer science. Students should work with their advisor to make sure that they both serve as a teaching assistant for the right classes, and have an appropriate thesis committee, for the kind of job the student desires.
