Field of work

My research focuses on water quality in aquaculture systems. Specifically, the effects reduced water quality can have on fish physiology, limiting factors in relation to water flow and how operational methods can affect both water quality in the system and the cleaning effect of the different water treatment steps in recirculation aquaculture systems (RAS).

My educational background and teaching experience ranges from aquaculture technology to offshore engineering, which is a driving force behind my interest in an interdisciplinary approach. I am currently project manager in an interdisciplinary competence enhancement project supported by NFR (RAS-EN 301828) that aims to expand the knowlege base relevant to education and research in the fields of energy-, ocean-, environmental- and aquaculture technology at Western Norway University of Applied Sciences.
