Summary
👤
Senior🎓
Top SchoolNis Jacobsen is a fisheries ecologist and senior researcher at DTU Aqua with a decade of experience applying size- and trait-based models to real-world stock assessment and multispecies management. He earned a PhD from DTU on size-based methods to evaluate direct and indirect ecosystem effects of fishing and has postdoctoral experience at the University of Washington and NOAA, where he focused on management strategy evaluation for Pacific hake under spatial and climate considerations. His work spans theoretical model development, simulation-based management evaluation, and practical ecosystem applications that balance biodiversity and yield. Nis brings a strong quantitative toolkit to marine ecology, combining statistical simulation, spatial structure analysis, and long-term monitoring datasets. Based in Copenhagen, he’s known for translating abstract size-structured theory into actionable advice for fisheries management. An often overlooked strength is his experience building functional trait databases early in his career, which underpins his comparative and cross-ecosystem perspective.
