Within the framework of the International Labex EFL Chair call, around ten professors or high-level researchers with international influence, specializing in one of the Labex research fields, can be awarded a Labex EFL chair each year.

The beneficiaries of the chair are welcomed by one of the Labex partner teams for 4 weeks and can enjoy its environment. They participate in the life of this team or of several Labex laboratories during their stay and can in particular be asked to discuss with the doctoral students of Labex EFL. They provide a two-hour weekly seminar at doctoral level on a research topic that significantly contributes to the EFL project.
