Driven by its humanist values and its stated ambition of openness, the University stands out for its strong international dimension, closely linked to the nature of its programmes and the dynamics of its research. This openness benefits both students and staff, whether they are teachers or administrators. The International Relations Department is committed to promoting mobility in all its forms – whether short or long term, face-to-face or hybrid – and to highlighting the many benefits that these experiences provide. Through this project, the University actively supports student and staff mobility initiatives. Student mobility is based on three modalities: 1/ long-term study mobility (one or two semesters) to Erasmus+ programme partner institutions, including as part of double degrees; 2/ international internships, which in some cases are essential for the validation of certain training courses; 3/ hybrid mobility, including studies, internships and intensive programmes. With regard to staff mobility, the focus is on sharing best practices and language training, as well as teaching mobility. These experiences enrich participants' cross-disciplinary and teaching skills, strengthen scientific collaborations and contribute to raising the institution's profile at European level. Staff mobility is therefore undeniably becoming an essential lever for the internationalisation of the university.
