As a research associate at the SLF in Davos, I spent around ten years researching the methodology of risk analysis for natural hazards and cost-benefit analyses of protective measures. This resulted in quantitative cost functions in avalanche protection (and a dissertation at ETH-Zurich and SLF-Davos on the topic of economic efficiency in avalanche protection), which are used to derive the society's willingness to pay for the prevention of mortality risks. Thanks to a practical guide, this risk approach has been widely applied in Switzerland, continuously developed and is now indispensable in dealing with natural hazards in the private and public sectors.

Since 2001 I have been intensively involved with the establishment of a unit on natural hazards in the canton of Graubünden and the implementation of hazard and risk basics to create the most effective products in practice. This integral risk management of natural hazards has always been confronted with limited resources and the principle "the longer it lasts, the society's demands for protection against natural hazards increases”. Dealing with three major risk situations over the last ten years in the canton of Graubünden has highlighted the challenges of risk management. Additionally I wrote a Master's thesis on risk management in private companies at the University of Zurich.

I have been retired since October 2023 and carry out individual consulting and teaching mandates.
