The Marie Curie Alumni Association (MCAA) is an association of researchers who have benefitted or are benefiting from a Marie Curie Action (recently renamed “Marie Skłodowska-Curie Actions” under the “Excellent Science” pillar of EU’s Horizon 2020 Programme for Research). Researchers on the verge of working on a Marie Curie project are also eligible to join. The main objective of the association is to provide its members with a space where they can share experiences and interests. Membership of the MCAA is open to past and current beneficiaries of the European Commission’s successive Marie Curie Actions (and earlier programmes) encouraging international mobility for researchers at: https://www.mariecuriealumni.eu/user/register
