Curriculum Vitae

Jeg har 25 års erfaring med studier knyttet til radioaktiv forurensning i norske kyst- og havområder, og har ansvar for dette fagfeltet ved Havforskningsinstituttet. Jeg leder Havforskningsinstituttets overvåkingsprogram for radioaktiv forurensning i det marine miljø. Overvåkingen gjennomføres i tett samarbeid med Direktoratet for strålevern og atomsikkerhet. I 2012 og 2014 var jeg toktleder for felles norsk-russiske tokt til henholdsvis Stepovogofjorden på Novaja Semlja, der det er dumpet store mengder radioaktivt avfall, og vraket av atomubåten K-159, som ligger ved utløpet av Murmanskfjorden i Barentshavet. I 2019 ledet jeg et tokt til vraket av atomubåten Komsomolets i Norskehavet, der vi benyttet ÆGIR ROV til å ta prøver av sjøvann, sedimenter og marine organismer i umiddelbar nærhet til vraket.
