PF: A current MSCA Postdoctoral fellow is interested in acting as a supervisor for an applicant in the MSCA PF 2023 call. Is this possible?

There are no explicit restrictions preventing a researcher who currently holds an MSCA Postdoctoral Fellowship from acting as a supervisor for an MSCA PF applicant. Assuming the role of a supervisor for an MSCA PF applicant may be demanding, as it requires a substantial investment of time and attention that may potentially affect the fellow's own MSCA project.

Furthermore, it is important to emphasize that the level of supervision (e.g., quality, experience, etc.) will be thoroughly evaluated by experts during the proposal evaluation stage.
