PF: Is a marital relationship between an applicant and the main supervisor considered a conflict of interest? Does it create any restriction or eligibility issue regarding the submission, evaluation, or implementation of an MSCA PF proposal?

Although supervision can be built on an existing collaborative relationship, the supervisor’s choice should be driven by the added value to the project. The applicant needs to justify the complementarity between their profile and the supervisor’s expertise, and if they have already worked together, they will need to explain what new techniques, methods, or specialised knowledge they will acquire that they have not already gained from previous common activities. Unless they can justify their supervisor’s choice (e.g., unique expertise, specific training needs, intersectoral added value, etc.), this could be viewed as a convenient choice that could affect the evaluation of the proposal.
