I am a dedicated marine biologist and population geneticist. I have been working with biology (mostly at a marine molecular level) since I finished my master degree in marine biology/ population genetics at NTNU in 1999. In recent years I have been working on a PhD thesis entitled “Genomic divergence in Atlantic cod populations” which was submitted in December 2016 and defended in early April 2017. I currently work as a PostDoc at Centre for Coastal Research at the University of Agder. Over the years, I have been involved in a large amount of projects that covers a vide variety of research on animals, plants and humans. In addition to my own research, that primarily covers marine genomics (mostly Atlantic cod and salmon), I have been involved in several human genomic projects focusing on deceases (like cancer, diabetes, migraine), forensics and ageing. I have also experience in projects dealing with artificial selection and traceability within production animals (sheep, goat, cattle and pig) and several plant projects. –All of these are central Life Science projects, using genomics and genomic variation, often based on NGS data.

I am currently working as a PostDoc at Centre for Coastal Research (CCR) at the University of Agder, working with population genomics in haddock (Melanogrammus aeglefinus) and two invasive crab species; red king crab (Paralithodes camtschaticus) and snow crab (Chionoecetes opilio). -In addition, I am also conducting some population genomic work on Atlantic cod.
