Since its creation, the Bézout Labex has hosted a number of invited professors, for stays of one month or more (possibly spread across several years). The Bézout Labex makes such visits particularly flexible.

Interested in joining the Bézout Labex as invited professor? Please contact a researcher in your field in one of the three laboratories CERMICS, LAMA, and LIGM. The deadline for applications is typically in December of each year. See also some practical informations on the academic environment.
