Background and activities
I’m a professor in Microbial Ecology with general interest in aquatic ecosystems - both natural and un-natural (human created).
Areas of speciality/Fields of responsibility
- Professor in microbial ecology
- Leader of the research group "Analysis and Control of Microbial Systems" with Kjetill Østgaard
- Teaches TBT4110 Microbiology, BT8101 Microbial Ecology, AK8000 Marine juvenile technology
- Involved in the projects HARVEST, OCEAN CERTAIN, Solbiopta, ThraustoEng, GnotoCod
I’m a professor in Microbial Ecology with general interest in aquatic ecosystems - both natural and un-natural (human created). Besides basic aspects, I’m interested in applied microbial ecology which can be placed under the heading Environmental Biotechnology.
