Department: Dyphavsarter og bruskfisk

Greenland halibut population structure and migrations, Arctic ecosystems, population modeling, statistics, and programming.

Curriculum Vitae

Numeric ecologist and scientific diver working with population ecology and assessment of deep-sea and cartilaginous fish. I have a broad experience in marine biology and have worked with all trophic levels, from primary production to seabirds and sharks. R programming, statistics, data-handling and analyses are my strengths, but I enjoy my work the most out in the field.

I am the stock coordinator and assessor of Atlantic halibut at IMR. In addition, I am a work-package leader for stock assessment within the deep-sea and cartilaginous fish group. Further, I am also in charge of running the stock assessment model for Greenland halibut.
