Research Professor
Jan Grimsrud Davidsen is a Research Professor in the Department of Natural History at NTNU University Museum. His research focuses on migratory behavior, habitat use, and life history strategies of anadromous fishes, particularly sea trout (Salmo trutta) and Arctic charr (Salvelinus alpinus). He employs methods like acoustic telemetry and stable isotope analysis to study how anthropogenic activities and environmental changes impact marine migrations. Key collaborations include projects with the Norwegian Institute for Nature Research, Dalhousie University, and the French Polar Institute. He leads the 'Freshwater Ecology' research group, emphasizing salmonid ecology and freshwater biodiversity. Recent work includes studies on pathogen effects on migration, Arctic charr behavior in Greenland, and the impacts of aquaculture on wild fish populations. Publications span 2013–2025, covering topics from marine migration patterns to conservation genomics. His work bridges basic research with applied management, addressing challenges like climate change and habitat restoration. Awards and grants are not explicitly listed in the provided text. Supervised students include Rasmus Rødne Lange, Lina Gjerdevik, and Rachel Coffey. Projects often involve interdisciplinary approaches, combining field studies with laboratory analyses to understand ecological dynamics in freshwater and marine ecosystems.
