Area of research: My research covers studies of fundamental aspects of soft matter and new soft materials for energy applications. The work includes investigations of non-equilibrium transitions, such as the glass transition and colloidal aggregation, charge and mass transport, hydrogen bonded systems, and vibrational excitations.

A particular focus is put on ionic liquids that have several intriguing properties including negligible vapor pressure, high electrochemical stability, and high conductivity. We study both neat ionic liquids and ionic liquids in polymer membranes, colloidal dispersions, and ionic liquid/Li-salt mixtures for Li-batteries, with respect to the influence of anion/cation structure on ion transport, phase behavior, glass transition temperature, and their use as solvents in colloidal silica gels.

By combining spectroscopic methods we access the relevant time and length scales. In-house laboratories include Raman scattering, infra-red spectroscopy and photon correlation spectroscopy. At large scale facilities experiments are performed with quasi-elastic and inelastic neutron scattering, inelastic x-ray scattering, x-ray photon correlation spectroscopy.

Function within the Röntgen-Ångström-Cluster: I am member of the Swedish delegation (steering group). In particular I have had an interest in developing the use of coherent x-ray techniques within the Röntgen-Ångström-Cluster.
