Observatoire de Paris implemented this Erasmus+ project with the aim of strengthening the international dimension of its training and partnerships. The main objective was to offer its students the opportunity to carry out internships abroad, particularly in high-level research environments, thereby fostering their professional integration and intercultural openness. The project also sought to consolidate the links between higher education and research, especially at the doctoral level, as well as to diversify mobility destinations, including, where applicable and to a limited extent, beyond the European area.
