In my research I study how hydropower plants affect salmon migration from their reproduction in rivers to the main feeding habitat in the ocean. My main focus is on the downstream migration, which the Atlantic salmon (Salmo salar) conduct both as juvenile and adult. I study the possibility to guide salmon to alternative routes around hydropower plants, both in small-scale stream water aquarium but also in full-scale natural rivers with high resolution telemetry studies.

I am also apart of the Industrial Doctoral School at Umeå University, which includes an external partner outside academia. In my case this is the power company Vattenfall AB who through this collaboration wants to gain more knowledge on fish movement adjacent to hydropower plants and how to facilitate safer fish passages in the future.
