Who is an Investigator

The PHS Conflict of Interest regulations apply to all Investigators. An Investigator is the principal investigator, co-principal investigator or any other individual who is independently responsible for the design, conduct,or reporting of PHS funded research.

Principal Investigators are responsible for appropriately identifying individuals who meet this definition for each proposal and award. The NIH definition of senior/key person and Investigator are closely related. To assist with appropriate identification of Investigators, we have developed an Investigator Matrix that summarizes titles and roles and offers guidance to PIs.

MIT Guidance

PI/PD Project Director or Principal Investigator

Always

Always

Includes multi-PIs.

Co-Investigator

Always

Always

Are named at the PD/PI’s discretion. Are involved with the PD/PI in the scientific development or execution of a project. May include research scientists, senior research scientists and senior postdoctoral associates, although this is not common. The designation of a co-investigator, if applicable, does not affect the PD/PI’s roles and responsibilities.

Postdoctorals paid on research grants

Sometimes

Only if Senior/Key

 

In most instances, postdoctorals, while engaged in research, do so under the guidance and mentorship of a PI and do not meet the criteria necessary to be categorized as Senior/Key.

Principal Investigators should be judicious in identifying senior/key personnel. Misidentifying personnel as senior/key unnecessarily increases burden for the preparation of the application, submission of Just-in-Time information and annual reporting requirements, in addition to FCOI disclosure.

Graduate Students (RAs)

Rarely

Only if Senior/Key

Only in rare circumstances would a graduate student meet the criteria of Senior/Key.They are in training and conduct research under the guidance and mentorship of a PI

Other Significant Contributors (OSCs)

Never

Never

These individuals are typically included with "Effort of zero person months” or “as needed.” Per NIH, these are not acceptable levels of involvement for those designated as Senior/key Personnel.

Consultants

Infrequently

Only if Senior/Key

Consultants are individuals who generally provide a ‘fee for service’ and do not typically conduct research. They may provide insight and expertise to the PI but independently are not responsible for the design, conduct or reporting of research.In most cases, they do not meet the definition of investigator.

If a non-MIT employee is responsible for conducting research, that research should be conducted through their home institution and they should be included in the proposal as a subrecipient and, as such, are entitled to intellectual property rights. The PI on a subaward is considered an investigator, as defined by the PHS regulations.

Collaborators (unpaid)

Never

Never

Unpaid collaborators do not contribute measurable effort, do not meet the criteria of Senior/Key personnel.They should be included as OSCs.

Collaborators (paid) at MIT

Sometimes

Only if Senior/Key

Collaborators (paid) at Another Institution

Never

Never

Should be included in the proposal as a subrecipient.May be an Investigator at his/her home institution

Subrecipient PIs and Senior/Key Personnel

Always

Always

MIT requires that subrecipient Investigators comply with the FCOI policy of their home institution.To designate the lead investigator at a subaward or consortium site, the role of Subaward Investigator (instead of Co-Investigator) should be used.Select “Other” for the Project Role field and then insert the appropriate role descriptor in the Other Project Role field.

*Senior/Key Personnel:As identified in the grant application, progress report, or any other report submitted to the PHS. The program director/principal investigator (PD/PI) and other individuals who contribute to the scientific development or execution of a project in a substantive, measurable way, whether or not they request salaries or compensation.

**Investigator: The project director or principal investigator and any other person, regardless of title or position, who is responsible for the design, conduct, or reporting of research funded by the PHS, or proposed for such funding, which may include, for example, collaborators or consultants.
