Prospective PhD students as well as those already in the program are strongly encouraged to apply for external fellowships. In addition to the prestige associated with external support, the department's policy is to pay the student, whenever possible, a "supplement" that produces a 9-month stipend (during September-May) that is 25% higher than the standard departmental 9-month stipend.
The following is a (partial) list of external fellowships for doctoral students in computer science. Note that nominations for the IBM, Google, and Microsoft fellowships are submitted by the department, and the department can only nominate a limited number. Applications for the other fellowships are submitted by individual students.
A list of past fellowship winners from the department can be found on the PhD student achievements page.
