Key areas are studies of the properties of materials by scattering and simulation techniques. The main focus is on dynamics (diffusion and phonons) and kinetics of condensed systems, in particular metallic films, intermetallic alloys, as well as metallic glasses and fast ionic conductors. The author is interested in atomistic diffusion mechanism in intermetallic compounds, in nano-clusters diffusion in bulk metallic alloys and in diffusion and relaxation in thin layers and on the surface. The phonon spectroscopy forms the basis of dynamics studies in thin layers and in nanocrystals and of the growth kinetics and dynamics of nano-clusters on surfaces.

Key research tools are X-ray scattering, in particular X-ray correlation spectroscopy, nuclear inelastic-, resonant- and neutron-scattering methods. Most of experiments is performed on synchrotron radiation sources ESRF in Grenoble and PETRA in Hamburg.
