Biography
I received my diploma in physical chemistry at the University of Berne, Switzerland, in 1982 in the group of Prof. E. Schumacher. My PhD work was performed in the same group and I received the degree in 1986. In the following I joined the group of Prof. M. T. Bowers at the University of California, Santa Barbara, USA until 1990. Subsequently, I was appointed at the Paul Scherrer Institute in the General Energy Department. The main focus of the research was the investigation of fundamental reaction mechanisms in combustion. After that I joined the SwissFEL ALVRA group at the institute continuing cluster research and setting up a molecular beam source providing sufficient metal containing species for further investigations with soft X-rays at the ATHOS beam line.
Scientific Research

- Investigations of the fundamental reaction mechanisms of the inital steps of soot formation
- Generation and characterization of radicals and (metal-) clusters in a free-jet
- Investigations of collision-induced resonances in two-color resonant four-wave mixing
- Spectroscopic characterization of radicals by linear and nonlinear methods
- Exploring the complex electronic structure of small transition metal species by non-linear spectroscopic methods in the collision-free environment of the molecular beam
- Supervision of PhD and post-doc students granted by the approved research projects
- Organization of the European Conference on Nonlinear Optical Spectroscopy (ECONOS, 2002)
- Guest editor of the Journal of Raman Spectroscopy
