My research focuses on food webs, biodiversity and functioning of aquatic ecosystems. I am particularly interested in their responses to anthropogenic stressors (e.g. eutrophication, acidification, brownification, atmospheric nitrogen deposition, etc.) and climate change. My studies cover a broad range of ecosystems including coastal waters, rivers, ponds and lakes, and I frequently apply ecological tracers such as fatty-acid biomarkers and stable isotopes to investigate ecosystem processes and food-web dynamics in the changing environment. My on-going projects include:

• Impacts of nitrogen deposition on resource quality and pelagic trophic transfer in subarctic lakes.
• Responses in nutritional quality and trophic ecology of fish to lake brownification.
• Resource use and quality of arctic freshwater consumers in a warmer climate.
• Zooplankton as an integrated indicator of ecosystem health.
• Intra-specific variation in lipid composition of zooplankton across spatiotemporal scales.
• Species traits of lotic macroinvertebrates – latitudinal patterns and their use for circumpolar freshwater biodiversity assessment.
• Autochthony and niche partitioning of benthic fauna at shallow-water hydrothermal vents.
