Marie Skłodowska-Curie Actions (MSCA) are funding programs established by the European Commission to support research and innovation in Europe. They aim to enhance the career development and training of researchers at all stages, from early-stage to experienced researchers, by providing grants for mobility, training, and collaboration. The MSCA promote international and intersectoral cooperation, encouraging researchers to work across borders and disciplines. This initiative helps to strengthen the European Research Area by fostering a diverse and skilled workforce, ultimately contributing to scientific excellence and innovation in various fields.
