Who are the evaluators of the Marie Curie IEF proposals? Other academics ? How are they selected ?

They will be matched to the proposal according to their profile and to the abstract and keywords. They will for sure be in the general research area, but might not be in the exact same field of the proposal. It is (at least, officially) not possible to find out who evaluated the proposal afterwards, but you can find a list of former evaluators here:
