Senior Researcher, Swiss Federal Institute for Forest, Snow and Landscape Research (WSL)


I am a senior researcher at the interface of macroecology, biodiversity research, and climatology. My research focuses on how climate and biodiversity are linked in time and space. A focus of my recent work has been the development of algorithms to downscale climate data to the biologically relevant scales needed for ecological studies. I am currently studying how extreme weather and extreme events, such as megadroughts, affect vegetation and biodiversity. I have also done extensive work on the geography and biodiversity of mountain ecosystems with a specific focus on cloud forest ecosystems in the tropics and the biogeography of tropical islands.

In TipESM we will look at tipping points in mountain ecosystems. Our role is to quantify when, how, and if ecosystems in mountains can reach critical tipping points.
