As part of the engineering curriculum at ESPCI-PSL, students are required to complete an international mobility experience, which is a key component in enriching their academic and professional development. This mobility can take the form of a three-month academic internship in a research laboratory abroad or a six-month industrial internship within an international company. This international exposure is a cornerstone of their training, allowing students to broaden their knowledge, discover new working environments, and compare the skills and expertise acquired in France with different approaches to engineering practiced around the world. At the PSL International Relations Office, we support students in organizing their mobility projects once they have been officially nominated by their academic advisor and a host institution has been identified. While mobility within the European area is strongly encouraged, we are committed to providing tailored support and high-quality follow-up for all selected students, regardless of their destination.
