Background and activities
I am interested in evolution, systematics and biogeography, in particular of non-biting midges of the family Chironomidae (Diptera). My research focuses on taxonomy, biology, phylogeny, zoogeography and molecular systematics of genera and species in the tribe Tanytarsini, but I am also involved in work with other groups of animals and plants. Among these, tardigrades through the project Tardigrades in Norwegian forests.
The last few years I have been heavily involved in various projects testing and using DNA barcoding in biosystematics. I am currently chairing the Norwegian Barcode of Life network and project (NorBOL) which is a national research infrastructure on DNA Barcoding. NorBOL aims to develop a barcode reference database for Norwegian species to support barcoding in applied projects (such as EBAI). I am also involved in the COST action DNAqua-Net as member of the Management Committee and co-lead of the working group on reference libraries.
The last couple of years I have lectured courses in biosystematics, biogeography and molecular techniques (BI1002, BI2001 and BI8002) at the NTNU Department of Biology.
I am curator of Diptera, Hymenoptera, Arachnida and a few minor insect orders at the NTNU University Museum.
