My research profile
My research is focused on aquatic ecology and migrating salmonids. During my PhD education I worked with hatchery-reared Atlantic salmon and studied effects of different feeding regimes on the phenotype, the smolt migration, and the adult return rates. In my postdoc-project I’m looking at effects of genotype and growth on life history variation in Atlantic salmon. I have also worked with mapping possibilities for data collection for sea trout; environmental flows and effects on ecosystem services; and the process of constructing fish passage solutions in regulated rivers.
I find the academic working environment extremely stimulating and rewarding and I hope my work will contribute to the conservation of aquatic ecosystems.
I have given lectures both at the undergraduate and master level at SLU and elsewhere. Topics that I have covered are related to fish and wildlife census techniques (including handling and tagging of fish); fish farming and aquaculture; and hydropower and fish passage.
