Research interests:

Ecosystem ecology, community ecology, trophic cascades, herbivory-plant interactions, biodiversity, indirect interactions

I have a Cand. Scient degree (Norwegian equivalent to MSc) in wildlife ecology / tropical ecology from the Norwegian University of Life Sciences. I have also studied one year of population biology in Université de Bourgogne, France. I have earlier worked with research projects on effects of forest fires in lowland dipterocarp rainforest in Indonesian Borneo, on termites, ants and sun bears (Ursus malayanus). I have also studied the relationship between reproductive investment and antioxidant blood levels in great tits (Parus major) in France.

In april 2011 i completed my PhD thesis on effects of moose (Alces alces) browsing on several trophic levels: field layer vegetation, flower-visiting insects and birds, and how these effects are modified by productivity and supplementary feeding of moose. Read more about my PhD project: Indirect effects of moose on the birds and the bees.

Currently I am working on a project on forestry and moose, how to increase natural winter forage for moose and reduce browsing damage to forestry, through changing forestry practices.
