In the sections below are descriptions of the various academic research staff appointments. Also see Section 5.4 Procedures for Research Appointments for additional procedural information.
-
Postdoctoral Associates work under the supervision of MIT faculty members.
Appointments are of limited term and are designed for those who have recently received the doctorate.
Appointments are usually for not less than one term and are normally not renewed beyond a total of four years. This appointment category is comparable in purpose to the postdoctoral fellow, but is distinguished by the fact that the postdoctoral associate is employed by the Institute and afforded the benefits and privileges associated with staff employment. (See 5.3.2 Academic Research Staff Appointments. )
Incumbents are not accorded principal investigator status and may not use Institutional Time for Outside Professional Activities. For an exemption to this policy, view Roles without Permitted Time. As described in MIT Policies and Procedures, Sections 4.4 Conflict of Interest, 4.5 Outside Professional Activities, and 7.12 Conflict of Commitment, individuals must disclose any Outside Professional Activity that appears to be Reasonably Related to their Institutional Responsibilities in MyCOI-OPA+:
- Within 30 days of starting a new engagement or renewing an existing one
- If 12 months have passed since their last OPA disclosure
-
Postdoctoral and Research Fellows come to MIT with fellowship aid to develop their scholarly competence and work under the supervision of MIT faculty members.
This appointment category is comparable in purpose to the postdoctoral associate, but is distinguished by the fact that the postdoctoral fellow receives a stipend in lieu of salary and is not employed by the Institute. Although fellows are not eligible for all of the benefits available to employees, the Vice President for Research strives to mitigate the impact. For further information, see Benefits Eligibility for Postdoctoral Fellows
The postdoctoral fellow title is appropriate for those holding the doctoral degree, while research fellow should be used for those with comparable professional qualifications.
