Background and activities
I am Associate Professor of Biosystematics and Curator at TRH, NTNU University Museum (VM).
I use a phylogenetic approach to studying a range of biological aspects in various groups of plants and fungi (incl. lichens), from population to family level. I frequently include archived collections (i.e. herbarium/fungarium specimens) in my research and use recently developed statistical tools for data analysis.I lead the researcher group Integrative Taxonomy and DNA-barcoding (TAXA). I am member of the resercher groups Bio3D (NTNU) and ISOP (NHM, UiO).
MSc project in biosystematics / conservation genetics? We offer MSc projects on both plants and fungi. See this page for short description of ongoing projects.
