Curriculum Vitae

Doctor scientiarum at University of Bergen, 28 March 2003: Influences of artificial light on Atlantic salmon (Salmo salar L.) in seawater.

Scientist at Institute of Marine Research, Matre within research group Animal Welfare from 1995 to date.

My main focus has been studies on salmon behaviour and performance in commercial sea cages during fluctuating natural and artificial environments. As an authority in this field, a compilation of this research is accepted as a review to the journal Aquaculture and will soon be available.
