I am a Senior Research Scientist in the Department of Terrestrial Ecology at the Norwegian Institute for Nature Research (2017 to present). I was previously a Professor of Wildlife Ecology in the Division of Biology at Kansas State University (2001 to 2017). My research interests are in population biology and wildlife management, especially with grouse, arctic-breeding shorebirds, and grassland birds. I have skills in quantitative ecology, including vertebrate demography, mark-recapture statistics, and matrix population models. My projects have included long-term studies of species of conservation concern, and manipulative field experiments to understand the ecological drivers of population dynamics.
