Academic interests
I am an ecohydrologist who studies the impact of climate change on Arctic-Boreal ecosystems. The northernmost part of our planet is warming much faster than the rest of the globe, leading to extreme temperatures, loss of snow cover and more frequent droughts. These changes affect plant growth and permafrost thaw, which in turn may cause the release of greenhouse gases to the atmosphere. Since these dynamics have the potential to enhance climate change, I study how and why the flows of water and carbon are changing across the landscape.
In my research, I draw from a long experience in the field, in northeast Siberia, Greenland, Scandinavia and Svalbard, to derive new insights from satellite data and to advance model development. This has given me a broad understanding of northern ecosystems, which I call on as a regular columnist in the Norwegian newspaper Klassekampen, and in my role as an Associate Editor at the AGU journal JGR:Biogeosciences.
