My research focuses on how individual development and body growth governs ecological dynamics in fish communities and aquatic ecosystems, and often in the context of environmental change. I work in a wide array of study systems, including lakes in Sweden and North-America and marine systems in the Baltic Sea. Methods include experiments, observations and mathematical modeling.


I am leading the postgraduate course in Fish and Fisheries Ecology and the MSc course Ecology for Fish Management and Conservation

I also teach on several other courses in e.g. Applied Conservation Biology (BSc), Sustainability Ecology (BSc) and regularly on postgraduate courses on topics such as community ecology and scientific writing.



Many of the projects I am currently working on aims to add understanding about how interacting human pressures and climate change may impact aquatic resources  by linking physiological responses to community-level impacts. 

Specific study topics include:
  -  Implications of environmental gradients for coastal food-web processes
  -  Fish community responses to rising temperatures and darker waters
  -  Resource partitioning over life history in fish
  -  Size-dependent herring-salmon interactions and bioaccumulation of
