I am very interested in what happens with nature now that we have entered the Anthropocene. Multiple stressors such as harvesting and climate change may lead to unexpected consequences for the marine and terrestrial populations and ecosystems. I have been working with contemporary human-induced evolution, particularly fishing-induced evolution and often combine this with fisheries management problems. World’s fish stocks show drastic changes in key life-history traits such as size and age at maturation, growth and reproduction, and these changes are likely not only plastic but also have a genetic component. But what is the combined effect of human harvesting and changing climate for individual phenotypes, genotypes, life-history strategies, population-level processes, and ecosystem services? I am currently PI in two projects financed by the Research Council of Norway, and one of them is trying to answer the questions "Can contemporary evolution explain the many enigmas in recent dynamics of Norwegian spring-spawning herring?" The project aims to disentangle the roles of fishing-induced evolution and phenotypic plasticity in relation to effects of density dependence and climate in determining phenotypic changes and population dynamics in pelagic planktivores.
Marine ecosystem dynamics are constantly changing, both because of natural fluctuations but also as a results of anthropogenic influences such as climate change and fisheries. My other project financed by the Research Council of Norway looks into "Ecosystem dynamics in the Norwegian Sea - new methods for understanding recent changes". In this project we aim at improving our understanding about the species interactions and the dynamics of the Norwegian Sea ecosystem by developing and using modern methods for identifying and quantifying the diet of these ecologically and economically important pelagic fish populations.
In my current position at the Institute of Marine Research as the head of the Research and Advice Programme Norwegian Sea I coordinate all research and advice related to Norwegian Sea.
I am the vice chair of the Young academy of Norway, an interdisciplinary organization for young researchers dedicated to research policy and dissemination. Young Academy of Norway was founded in October 2015 and currently has 20 members across discliplines and the country. Our aim is to be the voice of young researchers in the public arena.
I am an active member of the ICES community. I am a former chair the Working group on Widely distributed stocks (WGWIDE, 2014-2016), where Norwegian spring spawning herring, Northeast Atlantic mackerel, blue whiting, horse mackerel and boarfish are assessed. I have also chaired the group evaluating the long term management plan for Norwegian spring spawning herring (WKBWNSSH), and co-chaired the group evaluating the long term management plan of Atlantic mackerel (WKMACLTMP). I have also been active in the Herring Assessment Working Group for the Area South of 62° N (HAWG) where the herring and sprat stocks of the North Sea and surrounding areas are assessed, as well as the Working Group on Fisheries-Induced Evolution (WGEVO).
