Research interests

• Trophic interactions in aquatic food webs, in particular the role of long-chain poly-unsaturated fatty acids for invertebrate growth and reproduction
• Bioavailability, mobility, and ecological effects of sediment-associated contaminants (primarily pesticides) in aquatic ecosystems
• The use benthic invertebrates as indicators of environmental health/impact (e.g. acidification, eutrophication, pesticide use)
• Ecosystem effects of invasive species, i.e. Dreissena polymorpha and Gonyostomum semen

Ongoing projects

• Is ecological structure and function in Swedish agricultural streams impaired by pesticide contamination? – Research project funded by The Swedish Council for Environment, Agricultural Sciences and Spatial Planning (FORMAS).
• Liming effects on ecosystem structure, -function, and trophic relationships in lakes – Research project funded by the Swedish EPA.
• Efficiency in trophic transfer across the plant-invertebrate interface - The importance of polyunsaturated fatty acids. Research project funded by The Swedish Council for Environment, Agricultural Sciences and Spatial Planning (FORMAS) - In cooperation with Tobias Vrede, Uppsala University.
• Biological effects of pesticides Research project financed by the Competence Centre for Chemical Pesticides.
• Bioavailability of sediment-associated contaminants – The role of microbial exopolymers and humic coatings – Research project funded by The Swedish Council for Environment, Agricultural Sciences and Spatial Planning (FORMAS).
• Revision of Environmental Quality Criteria for benthic invertebrates – Monitoring and assessment project funded by the Swedish EPA.
