International mobility of students and staff is a key element to the implementation of Ecole des Ponts ParisTech overall strategy, in which one of the pillars is its international outreach. In this context, our main objectives were : - tightening links with our European academic partners, especially those belonging to EELISA European University, through inbound and outbound study mobilities, - offering our students more possibilities to improve their intercultural skills and employability, - increasing our links with EU companies through internship mobilities - improving staff intercultural skills and pedagogical methods through meetings with key partners Such objectives had a particular meaning since the project was taking place just after the COVID period, where mobilities had been dramatically reduced
