My main interests are to understand how environmental changes may induce changes in soil organism communities and assess the consequences of community changes for soil processes. More specifically, I am interested to what extent environmental changes affect interactions between soil fauna, microorganisms and plants, and if changed interactions lead to changes in carbon and nitrogen cycling. Most of my current projects are situated in arctic ecosystems, but I am expanding my research into boreal forests as well.

I try to answer my research questions using different approaches at different scales, e.g. in the laboratory, using mesocosms and small scale field experiments, and by larger-scale field sampling campaigns. Recent work includes studying how biotic interactions may alter the fate of soil organic carbon and nitrogen in thawing permafrost and how earthworm invasions may lead to dramatic changes in biogeochemical processes in arctic tundra.

I am course coordinator for, and teacher in the MSc course: 'Soil Biology and Biogeochemistry (15 ECTS)' that runs from January-March every year

I am study director for the PhD graduate school 'Focus on Soils and Water'
