Research interest

My general interests are fish ecology, population dynamics, population genetics, ecotoxicology and fisheries management. I have been working with projects coupled to different fish species and issues, mainly within two fields; the use of population genetic methods to understand how populations arise, at what geographical scales and why they become subdivided. Secondly, I have been investigating how environmental pollution affects fish, both at the individual level (fecundity) and population level by conducting population modeling.

Current research projects

Since 2012, I coordinate the research on the Swedish Great Lakes at the Institute of Freshwater research. The research is focused on monitoring and assessment of the state of the Great Lakes; Vänern, Vättern, Hjälmaren, Mälaren, and Storsjön. The research comprises for example stock assessment of fish, ecosystem analysis, development and assessment of protected areas, development of hydroacoustic methods to quantify pelagic fish, effects of fishing etc. Our unit conducts test fishing and the results are delivered yearly to the NORS database.
