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.

Arbeidsområde

• Bestandsvurdering av bunnfisk
• Vekstanalyser av otolitter
• Modellering av biologi tidsserier
• Effekter av klima, fisking og fiskebestand dynamisk
• Fiskeprøvetaker på bunnfisktokter
