The CRAN collaborates with more than 50 Universities and Research Centres worldwide. These collaborations materialize by bilateral or collaborative agreements through European or international research programs. Every year, several foreign scientists (professors, postdocs) are visiting researchers at CRAN for a few days up to several months.

Our partners
The international relation policy of the research center is governed by those of its heading entities: 
- the European research and international collaborations direction of CNRS
- the International affairs of University of Lorraine
