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 biogeochemical processes in terrestrial and aquatic ecosystems with special emphasis climate change effects in arctic and boreal environments.
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.
