I work as a researcher in the Demersal Fish research group, with a focus on monitoring and assessment of demersal fish stocks in the Barents and Norwegian Seas. I am stock assessor for Norwegian coastal cod north of 67ºN. My work include leading scientific surveys, participating in ICES working groups, and developing and participating in research projects. I am particularly interested in how predator-prey interactions drive population and ecosystem dynamics. In my PhD I used theoretical and statistical models to study the predator-prey interaction between cod and capelin, two commerically and ecologically important species in the Barents Sea.
