My main interests are to understand how environmental changes induce changes in soil organism communities and assess the consequences of community changes for soil processes. More specifically, I am interested to what extent these changes affect interactions between soil fauna, microorganisms and plants, and if changed interactions lead to changes in carbon and nitrogen cycling.

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.
