My main research interests are historical and contemporary plant dispersal and plant conservation. My work spans the fields of biosystematics, plant geography, conservation genetics and genomics, landscape genetics, vegetation ecology, and floristics.
I focus mainly on arctic-alpine and boreal plants, especially the rare, disjunctly distributed and/or threatened species. I also focus on alien species and their dispersal to and establishment in Norway and in the Arctic.
A selection of current projects I lead or am involved in:
Since 2002, I've been responsible for planning logistics, safety and carrying out botanical field expeditions in Arctic and northern regions:
Arktisk-alpin og boreal botanikk, biosystematikk, plantegeografi, bevaringsgenetikk, genomikk, vegetasjonsøkologi, floristikk.
