Presentation

I am a scientist and director of studies at SLU Aqua. My activities relate to coastal water environments and are quite broad - for instance stock assessment of eel and herring, modelling, ecosystem-based management, ecosystem services and marine spatial planning. In 2009 I was awarded the Linnaeus Prize by the Royal Society of Science.
