Organisation Profile
We study how soil carbon (C) and nitrogen (N) cycling processes change in response to global warming and aim to advance understanding of the underlying mechanisms. We work in different scales from field work on climatic gradients in high latitude and high-altitude ecosystems, to controlled mesocosm studies and laboratory incubations. Read more on our website.
