Background

Major research interests are in the fields of fungal and plant evolutionary biology and life sciences. My core research activities deal with ascomycete biosystematics/phylogeography, and plant-fungus (mycorrhizae; root endophytes) and insect-fungus (insect pathogens) interactions. For the past few decades we have taken advantage of using a spectrum of microbial techniques and molecular and phylogenetic approaches in our studies.  
I also have deep-rooted academic interests in the fields of human life sciences, toxinology and ethnobotany. In the period from 2003 through 2012 I was the elected Department Head at Department of Biology, University of Oslo (UiO) and is now returned to my professorship at Department of Biosciences, UiO.
