Fisheries ecology and aquatic resources  (Postgraduate course)

Kick-off your scientific writing (Postgraduate course)



My research focus on how individual development and body growth governs ecological dynamics in aquatic ecosystems. In particular, I am interested in the links between body size variation among individuals and the dynamics of the communities in which these individuals reside. I have worked in a wide array of study systems, ranging from lakes in Sweden and North-America to marine systems in the Baltic Sea. Methodological techniques include experiments, observations and mathematical modeling.

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 and their responses to fishing, 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
