Special interdisciplinary doctor of philosophy (Ph.D.) programs may be arranged for individual students who wish to pursue subjects that cut across the boundaries of program curricula.

A student who seeks the Ph.D. in an area requiring the services of two or more programs should consult interested faculty members and then submit a formal proposal to the dean of the Graduate School–New Brunswick outlining a program of study. Courses, examinations, the dissertation topic, and the names of faculty members who have consented to serve as the student's committee must have the approval of the directors of the Ph.D. programs involved. Once approved by the dean, the student will be transferred into the interdisciplinary Ph.D. program code (554) for registration purposes. A member of the Graduate School–New Brunswick academic staff serves as graduate director of this program.

Contact the Office of the Graduate School–New Brunswick, 25 Bishop Place, New Brunswick, NJ 08903, or call 848-932-7034 for further information.
