Application of optics to soft matter physics to understand physical properties under confinement, including vesicles properties, liquid crystals physics and applications to biophysics. We are interested in controlling flows and deformations by optics to better undertsand essential properties of matter. - Optofluidics and application of optics to soft matter (optical stretcher, biophysics, etc…) - Soft matter under confinement - Hydrodynamics - Liquid Crystals Physics
