Jeg jobber som numerisk modellør i Økosystemprosessgruppen, og har jobbet med flere store numeriske modeller for å studere påvirkning av ulike stressorer (klima, fiskerier, olje ++) på økosystemene i de Nordiske hav og Barentshavet. Dette inkluderer enklere næringsnettmodeller som primærproduksjon, detaljerte individ-baserte modeller (NORWECOM.e2e), hvor vi studerer fiskebåter som høster raudåte, til komplekse end-to-end modeller (NoBa Atlantis), som vi har brukt i flere studier som inkluderer endringer i forvaltning, klima og utslippsscenarioer. 

Arbeidsområde

  • Økosystemkonsekvenser av endringer i klima og forvaltning av fiskerier i Norskehavet og Barentshavet ved bruk av økosystemmodeller; både Nordic and Barents Seas Atlantis (NoBa) og NORWECOM.e2e. 
  • Økosysystemkarakterisering i datafattige områder, gjennom tema 11 i EAF Nansen

Research interest and experience: End-to-end and ecosystem models (in particular Atlantis and NORWECOM.E2E), mainly with focus on the Barents and Nordic Seas. Use these to explore combined climate and management scenarios, management strategy evaluations, ocean acidification, invasive species and the effects of these on the ecosystem structure and function. Ecosystem characterization and ecosystem based approaches to management in regions with varying intensity of monitoring.
