Postdoctoral appointments are temporary positions with fixed end dates intended to provide a full-time program of advanced academic preparation and research training. A postdoctoral appointment is not intended for long-term, indefinite, or career appointments, or for short-term appointments where the primary goal is to advance a principal investigator’s research. Postdoctoral Researchers train under the direction and supervision of a faculty or other qualified mentor in preparation for academic or research careers.  In addition to pursuing advanced preparation in research, Postdoctoral Researchers may be approved to engage in other activities to enhance teaching and other professional skills. To be the instructor of record in a course, a Postdoctoral Researcher must hold both a Postdoctoral Researcher title and an appropriate teaching appointment. Ordinarily, Postdoctoral Researchers are not permitted to serve as principal investigators on contracts or grants sponsored by agencies external to the University.
