I am a Senior Research Scientist in the Department of Terrestrial Ecology at the Norwegian Institute for Nature Research.  I have been working as a project leader for two international research networks focusing on options for renewable energy in Norway, and drivers of bird distributions in Fennoscandia.  My research interests include population ecology, conservation biology, and wildlife management, and I work mainly with terrestrial vertebrates in arctic and alpine ecosystems. I have an interest in quantitative ecology, including vertebrate demography, mark-recapture statistics, and matrix population models.  Recent collaborative projects with NINA colleagues have included monitoring for cesium levels in alpine plants, early detection of invasive species of plants and insects, demographic studies of migratory waders, and population models for arctic fox.
