My main research interests are historical and contemporary species 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 on alien species and their dispersal to and establishment in Norway and in the Arctic. I also focus on arctic-alpine and boreal plants, especially the rare, disjunctly distributed and/or threatened species.
A selection of current/recent 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:
Arctic-alpine and boreal botany, biosystematics, plant geography, conservation genetics and genomics, vegetation ecology, floristics. Alien species: monitoring occurrences and pathways, identification of door knockers, and risk assessments.
2010: PhD in Biology, University of Tromsø (UiT).
Specialization within arctic-alpine and boreal vascular plants and bryophytes: conservation genetics, biosystematics, statistical phylogeography, molecular markers, GIS and remote sensing data.
Thesis: Disjunctly distributed arctic-alpine plant species - phylogeography and conservation genetics in a changing world.
Project: "Did vascular plants and bryophytes survive the last ice age in Scandinavia?" (NRC project 170952/V40 to Prof. Christian Brochmann, National Centre for Biosystematics (NCB), University of Oslo)
2004: Cand. scient. in Vegetation ecology/geobotany, UiT.
Thesis: Phylogeography of the high arctic Saxifraga rivularis L. inferred by Amplified Fragment Length Polymorphisms (AFLPs).
Project: "Effects of climate change on ecosystems in Svalbard: past and future immigration of thermophilous key species" (NRC project 150322/720 to Prof. Christian Brochmann, National Centre for Biosystematics, University of Oslo)
