Special focus within my research lies within studying the importance of organic matter (humic substances) and nutrients (nitrogen and phosphorus) for lake ecosystem productivity and food web structure. My current research projects concern how global climate change are affecting lake water biogeochemistry, and what possible impacts these biogeochemical changes have on lake productivity and the ecosystem services of northern pristine lakes. We assess how nutrient availability and the N:P stoichiometry in lakes are affected by changes in atmospheric nitrogen deposition and by warming, and its effects on nutrient limitation of phytoplankton and zooplankton, nutrient regeneration and trophic transfer efficiencies, and productivity in northern boreal and subarctic lakes.

My research is linked to Arctic CIRC (Climate Impacts Research Centre)
