Education and work experience: Graduate studies in Physics at Jagiellonian University in Krakow; 1983 Master's Thesis; 1989 Doctoral thesis at the Institute of Nuclear Physics in Krakow; 1990 Post-Doc at the Institute of Solid State Physics, University of Vienna; 1992 research assistant at the Institute of Solid State Physics; 2001 habilitation for experimental physics at the Institute of Solid State Physics; 2002 ao. Univ.-Prof. at the Institute of Materials Physics at the University of Vienna.

Key areas of research 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.
