Has done extensive research on land use conflicts in a socio-economic and socio-cultural perspective, cultural change in rural areas, and local resource management. Adept in qualitative as well as quantitative methods. Extensive popular dissemination.
Research Ecologist Field of work: Vegetation ecology, botany, population ecology, population genetics, conservation biology, species and area management, agricultural landscapes, environmental impact assessments, landscape analysis, geographic information systems (GIS).
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.
