Supervision Activities 50 Students in Master Degree 11 Students in PhD Thesis Scientific Activities: My research activities mainly concern the field of the physics of glasses, physics of disordered matter and more particularly the physics of polymers and nowadays of biopolymers. I work more specifically on the study of dynamics in amorphous phases, mainly in polymers but also for other glass formers. The various works that I have implemented, or in which I have participated, are at the intersection of two issues: - A more fundamental theme which aims to understand the physical mechanisms and the laws of behavior for glass-forming liquids below and above the glass transition temperature. - A theme with a more "materials" approach aimed at studying the impact of modifications of amorphous phases, in a physicochemical manner. This produces different relaxation environments. The principle of the environment is seen here in the broad sense since under this term we can group together: - microstructures in the case of semi-crystalline polymers - geometric confinement - fillers or nano-fillers in the case of composites - additives - nano-texturing ... These two approaches are most often interconnected in my work since the fundamental understanding of relaxation phenomena in amorphous "model" materials allows a more precise reading of the phenomena observed during an application on more complex materials.
