Research activities
My research focuses on the study of the physical properties of soft objects: polymers, membranes ... I am interested in the physics of polymers at interfaces, both experimentally (stick-slip instability of polymer melts dynamic polyelectrolyte multilayers) and theoreticaly (mechanism of energy dissipation in friction polymer). In recent years, the central part of my work involves the study of the physical properties of lipid membranes: structure, fluctuations, destabilization and internal dynamics. In particular, as part of a collaboration with J. Daillant recent years have led to a major experimental and theoretical development to enable the study of single model membrane by diffusion of radiation. This allowed us to access for the first time the fluctuation spectrum of a single membrane in the submicron range. Finally, always in the spirit of understanding at the microscopic level the macroscopic properties of dense matter, I am recently interested in the elastic properties of a fiber system.
