Research

The experimental research in this group addresses the dynamics in disordered materials such as liquids, organic supercooled liquids, polymeric materials, solid state ionic conductors, ionic liquids, and glassy systems. We are interested in understanding the motion of molecules and charges on a microscopic scale, and how it relates to the macroscopic properties of these materials.

Our research topics cover the phenomena associated with glass transitions, geometrical confinement on nanometer scales, interfacial effects, spatial heterogeneities of the dynamics, details of relaxation and retardation processes and of molecular dynamics, and the relation between macroscopic and microscopic behavior.
