My primary research goals are directed towards evaluating human and climate impact on ecological and biogeochemical processes using radionuclides as tracers. I have expertise in both terrestrial and aquatic ecosystems at various temporal and spatial scales.

Special focus within my research lies in studying the importance of organic matter (humic substances) and nutrients (nitrogen and phosphorus) for lake ecosystem productivity and food web structure.

My research focuses on the controls over ecosystem structure and functioning in streams, rivers, and watersheds. We study these systems to understand their condition as natural resources, but also as models to test general ecological and biogeochemical principles.

I am a plant ecologist with a passion for the ecosystems of cold areas. I am fascinated by their characteristic plant communities and by the plants’ abilities to survive harsh conditions through manipulation of their neighbours and their micro-environment.
