Picture press release
Forsker
Telefon: 46544931
Avdeling: Bunnfisk

Forsker i bestandsvurdering og forvaltning for bunnfisk resurser.

Jobber hovedsakelig på Nordsjøen hvor jeg er bestandsansvarlig for torsk, og i mindre grad involvert med hyse, lyr og rødspette.

Etter PhD forskningen min, også interessert i Nordøstarktisk torsk og klimaendringseffekter på fisk biologi.

Involvert i kvalitetssikring for alderlesning, og forsker på bruk av otolitter og otolittarkivet for å studere fisk økologi, ved bruk av vekst mønster, otolittform, isotoper og mikrokjemi.

Amatør natur og fuglefotograf i fritiden.
