Telefon: 47489981

I am a fisheries biologist, holding a PhD in the trophic ecology of small pelagic fish and an MSc in Ecology, Management and Protection of the natural Environment. I am currently employed as a researcher at the Center for Development Cooperation in Fisheries, at the Institute of Marine Research in Bergen, Norway. 
Throughout my professional career, I have been involved in:

  • Trophic ecology of small pelagic fish
  • Species distribution modeling of fish
  • Early life stages of fish
  • Fisheries oceanography
  • Management Strategy Evaluation

Additionally, I have participated in numerous research projects and currently involved in the theme 2 'Pelagic stocks distribution, abundance, trends and dynamics, stock identity and ecology' of the EAF-Nansen Program, as a co-theme leader.
