Graduate students may not be Principal Investigators, but may serve as co-Principal Investigators. If a graduate student will become a Post Doc at OSU at the commencement of a proposal, the student can be listed as a Principal Investigator. However, this requires verification by the department through a letter indicating their appointment and start date. (Note: graduate students may not simultaneously be an OUS faculty member and an OUS graduate student (OAR 580-20-005). If an OSU unit violates this policy and hires a graduate student as an instructor (simultaneously), they may not serve as a principal investigator.)
