Main scientific experience covers population and habitat ecology of small mammals in boreal forests and mountain ecosystems. Applied research and consultancy work includes studies and assessments of boreal forest ecology, protected areas, ecological effects of agriculture and forestry on species and ecosystems, environmental impact assessments of infrastructure development projects, as well as assessments, indicators and monitoring of terrestrial biodiversity.
Main administrative experience covers management of NINA's research department in Oslo over > 25 yrs, as well as coordination of terrestrial ecosystem monitoring and major research projects and programmes on boreal forests or cultural landscapes.
Major practical experiences cover project management concerning research and monitoring in freshwater (rivers and lakes) and in marine environments (estuarine and coastal waters). Specialization on freshwater biodiversity and water quality. Project leader for several national projects on implementation of the EC Water Framework Directive in Norway: Design of a National Monitoring Network for Reference Sites, Design of a National Network for Surveillance monitoring in freshwaters, Evaluation of methods for monitoring and assessment of freshwaters c.f. the WFD. Experience from international work on standardization of biological methods, and different aspects related to the implementation of the ECC’s Water Framework Directive.

I have extensive experience with research on and monitoring of freshwater mussels in Norway, Canada and the USA. As a part of this work I have also worked with confirmed and potential host fish for these mussels. Therefore, I have gained experience with a variety of freshwater fish, both through experiments and field work. In additiont to working on parasite-host interactions between mussel larvae and fish, I have also worked on evolutionary theories on parasites that castrate their hosts. Specifically, I worked on a bacterium that castrates water fleas (daphnia).
