Presentation

I am a researcher and director of studies at SLU Aqua. My activities mainly relate to coastal water environments and include stock assessment of eel, modelling, ecosystem-based management, ecosystem services, evaluation of test fishing, and green infrastructure. Since 2018 I am an Academic Editor for the journal PLoS One. In 2009 I was awarded the Linnaeus Prize by the Royal Society of Science.
