Young Researchers Seminar

At CERMICS, we organize roughly every two weeks a seminar for the young researchers, ranging from interns to post-docs. The subject and the format of the presentation are varied, and the seminar is open to everyone who is interested : if you are external to the lab, contact one of the organizers to arrange your visit !
