I am Research Scientist in the Mountain Ecosystems research group at the Climate Change, Extremes, and Natural Hazards in Alpine Regions Research Centre CERC. The CERC is part of the WSL Institute for Snow and Avalanche Research SLF in Davos, Switzerland.

As a forest ecologist, I am interested in the influence and interaction of climate change, disturbances, and management on forest ecosystems. My research benefits from different types of data, based on a data fusion approach, and from the combination of different methods.

Strongly influenced by my professional activities as a forester, I value much the engagement and interaction with local stakeholders and practitioners, as well as the communication to and with the public.

Research interests

Impact of climate change and natural disturbances on mountain forest ecosystems, protective forests, ecosystem services, forest management, silviculture, forest adaptation strategies, dendroecology.
