Curriculum Vitae

Jeg har mange års erfaringer med fiskeribiologisk bestandsvurdering og rådgiving, og var i ca 15 år  bestandsansvarlig for blåkveite og vassild både i HI og ICES og hatt ansvar for tannfisk i sørishavet i senere år, I ICES har jeg primært deltatt i arbeidsgruppene AFWG og WGDEEP i mange år, inklusiv å lede WGDEEP i 6 år. Jeg ledet også arbeidsgruppen WGNEACS i 3 år. Jeg har omfattende tokterfaring, på HI hovedsakelig som toktleder. På HI toktene har jeg også hatt ansvar for de akustiske undersøkelsene. Via prosjekter har jeg i tillegg vært involvert i økosystemundersøkelser, der jeg i et tilfelle ledet en arbeidspakke. Har erfaring med prosjektledelse ved HI.
