MSCA fellowships are among Europe’s most competitive and prestigious awards and aims at supporting the most promising scientists - as well as helping to attract the best foreign researchers to work in the EU. Support is given to experienced researchers, i.e. in possession of a PhD or with at least 4 years of research experience to enhance the mobility of the researcher abroad through European Fellowships within the EU Member States and Associated Countries (of two years) and Global Fellowships outside of Europe (of three years). The grant usually covers salary, research costs and overheads for the host institution. Individual researchers submit proposals for funding together with their host organization and are judged on their research quality, career prospects, and the support offered by the host.
