My research focus on the importance of predator-prey interactions for individual performance and population dynamics of predatory fish and their ecological function in aquatic systems. I also work with European eel management within the unit of diadromous fish at SLU Aqua since 2022.
2020: PhD in Marine Ecology, Swedish University of Agricultural Sciences (SLU): "Size-dependent predator-prey interactions, distribution and mortality in salmon: effects on individuals and populations"
2015: MSc degree in Marine Ecology, Stockholm University, Sweden.
