Dense colloidal suspensions are model systems for the study of glass transition. We are interested in colloidal suspensions of soft spheres that can be designed with particles of varying deformability and interactions. This allows us to obtain a wide variety of behaviours to reproduce the glass transition.
We are interested in aging, heterogeneous dynamics and fluctuation-dissipation relations.
