Scientific achievements:

- Development of innovative light scattering techniques: I was among the pioneers of multispeckle light scattering. I've introduced new space and time-resolved dynamic light scattering methods now used by several groups.

- Glassy colloidal hard spheres: I have experimentally demonstrated that there is no glass transition "à la mode coupling".

- Non-diffusive slow dynamics in glassy/jammed soft matter: I discovered unusual ballistic dynamics in out-of-equilibrium soft materials, now believed to be quite general, including in metallic glasses.

- Dynamical heterogeneity: I showed that the slow dynamics of glassy/jammed soft materials is quite generally heterogeneous in space and time, in analogy to theoretical predictions for molecular glass formers.

- Sedimentation of colloidal suspensions and gels: I've shown that velocity fluctuations in settling suspensions may be non-stationary, thereby rationalizing previous contradictory results. I quantitatively tested theoretical predictions for the macroscopic behavior of settling gels (poroelastic model) and established a relation with their microscopic dynamics
