welcome at my home page and get a glimpse of my scientific activities.

I recently accepted happily the offer of a full professorship in experimental physics at the University of Rostock. The new group will be started in October 2007. The research will cover two major areas. One is fundamental processes in molecules and the other dynamics in organic materials and multicomponent systems. This icludes electronic excitations in aggregates, charge separation in heterojunctions, and exciton dynamics in polymers with a high regularity.

A couple of positions for diploma and PhD students are available. If you are interested, please contact me by phone or email.

The focus of my scientific interests lies in molecular dynamics including

• coherent wavepacket motion in reactive systems,
• mechanisms of prototype reactions like intramolecular proton and electron transfer,
• energy and charge transport in systems for organic electronics
• multidimensional character of molecular phenomena, e. g. micro irreversibility,
• electronic relaxation mechanisms and, in particular, the role of conical intersections.

To observe these processes in real time we use pump-probe absorption spectroscopy with a temporal resolution of 20 fs. For the investigation of electronic configuration changes we apply in addition photo electron spectroscopy in close collaboration with Albert Stolow and his coworkers (Ottawa, Canada)

The techniques relay on the availability of laser pulses in the visible and ultraviolet spectral region with a duration in the order of 10 fs. In this context we work on

• pulse sources and conversion schemes to enter new spectral and temporal regimes,
• precise characterization methods like ZAP-SPIDER
• full control over the spectral phase to generate clean bandwidth limited pulses as well as complex pulse sequences. We want to use the later to steer molecules by optical excitation in a desired process channel.

In my spare time I like to go hiking or to make a bicycle tour through the surrounding areas of Munich. In winter my interests shift to back country skiing.
