All students in the Ph.D. program receive, for up to five years, a funding package consisting of tuition, fees, and a stipend. These fellowships are awarded in recognition of academic achievement and in expectation of scholarly success; they are contingent upon the student remaining in good academic standing. Summer support, while not guaranteed, is generally provided. Teaching and research experience are considered an important aspect of the training of graduate students. Thus, graduate fellowships include some teaching and research apprenticeship. Ph.D. students are given funds to purchase a laptop PC, and additional computing resources are supplied for research projects as necessary. The Department also subsidizes up to $750 of travel expenses each year for students who make presentations at scientific meetings. Additional matching funds from the Graduate School Arts and Sciences are available to students who have passed the oral qualifying exam.
