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:
- Import of plant products to Norway: mapping and monitoring alien hitchhikers (2014-2018; PI)
- Ecological risk assessment of alien vascular plants in Svalbard and Jan Mayen (2018)
- Non-native vascular plants in the Arctic - diversity, characteristics and biogeography (2017-2018)
- Arctic Alien Species - risks, trends and pathways (2017-2018)
- Towards conservation genomics: studying ‘migration of adaptation’ in a threatened non-model plant species (2014-2019; PI)
Since 2002, I've been responsible for planning logistics, safety and carrying out botanical field expeditions in Arctic and northern regions:
2018 Svalbard, East Greenland, Iceland
2016 Northeast Greenland National park, USA (Alaska, Colorado, Minnesota), northern Norway
2014 Northeast Greenland National park, USA (Alaska, Colorado, Minnesota), northern Norway
2011 Middle and southern Norway
2009 Svalbard, Finnmark
2008 Nordland, Troms
2007 Northeast Greenland National park, Iceland, Scotland, northern Norway
2006 Svalbard, West and South Greenland, northern Norway
2004 Northern Norway, West Greenland and Arctic Canada
2003 Svalbard, northern Norway
2002 Svalbard, northern and southern Norway, Chile
