The Marie Skłodowska-Curie Actions (MSCA) are a set of European Union initiatives aimed at supporting research training, career development, and knowledge transfer. Among these, the Innovative Training Networks (ITN) are designed to train Early-Stage Researchers (ESRs) through international and interdisciplinary collaborations. The primary objective of ITNs is to enhance the career prospects of researchers by providing high-quality research training and promoting mobility and skills development.
