MSCA Doctoral Networks (DN) is part of the European Union’s Marie Skłodowska-Curie Actions (MSCA) programme, which supports excellence in doctoral training through international, interdisciplinary, and intersectoral research collaboration. Doctoral candidates are recruited into international research networks that bring together universities, research institutes, companies, and other organizations across Europe and beyond. The programme promotes researcher mobility, advanced scientific training, and the development of transferable skills, preparing doctoral candidates for diverse careers in academia, industry, and the public sector. Through international exchanges and collaborative research, participants gain valuable experience, expand their professional networks, and contribute to addressing key scientific and societal challenges.
