About
Research interests
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 and basic reserach. I am also coordinating the work package on sampling for barcoding in the Horzon Europe funded project Biodiversity Genomics Europe and represent Norway in iBOL.
I am leading the reseach group on Integrative Taxonomy and DNA Barcoding (TAXA) at the Department of Natural History.
I study biodiversity, evolution, and how species are related and distributed in nature. A central focus of my research is non-biting midges (Diptera: Chironomidae), a highly diverse and ecologically important insect group found in nearly all freshwater ecosystems. Although small and often overlooked, they play key roles in ecosystem functioning and are widely used as indicators of environmental change and climate impacts.
My research combines classical taxonomy, including species description and identification, with modern molecular approaches to investigate evolutionary relationships, species boundaries, and biogeographic patterns. I work particularly on midges, but my research also includes other organism groups such as tardigrades.
In recent years, I have focused extensively on DNA barcoding, a method that uses short DNA sequences to identify species. DNA barcoding enables faster and more accurate biodiversity assessment and is an important tool in environmental monitoring, conservation, invasive species management, and applied biological research.
I lead Norwegian Barcode of Life (NorBOL), a national network of 17 institutions collaborating to build a comprehensive DNA barcode reference library for Norwegian species. NorBOL serves as the national infrastructure for DNA barcoding in Norway and supports basic research, education, and applied projects in collaboration with environmental authorities and industry partners.
I represent Norway in International Barcode of Life (iBOL), contributing to global efforts to build a DNA-based reference system for life on Earth. I also participate in the Horizon Europe–funded project Biodiversity Genomics Europe (BGE) and its follow-up initiative BGE Plus, which aim to advance large-scale genomic approaches for biodiversity research and monitoring across Europe.
In addition, I lead the research group TAXA, which focuses on taxonomy, systematics, and biodiversity research using integrative approaches that combine fieldwork, morphology, and molecular methods.
I supervise students at the bachelor’s, master’s, and PhD levels and welcome projects addressing biodiversity, systematics, and evolutionary questions.
Teaching
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.
Scientific collections
I am curator of Diptera, Arachnida and a few minor insect orders at the NTNU University Museum.
Research
Biodiversity Genomics Europe (BGE)
BGE will accelerate the use of genomic science to enhance understanding of biodiversity, monitor biodiversity change, and guide interventions to address its decline. BGE is funded by Horizon Europe and coordinated by Naturalis Biodiversity Center.
Norwegian Barcode of Life (NorBOL)
NorBOL is the Norwegian National Research Infrastructure for DNA barcoding.
Tardigrades in Norwegian forests
Funded by the Norwegian Biodiversity Center's Taxonomy Initiative, this project has as goal to document tardigrade diversity in different forest types in Norway and analyse community characteristics of different substrates.

I coordinate the Nordic Academy of Biodiversity and Systematic Studies (NABiS) master’s programme, an international and English-language Nordic collaboration in biodiversity and systematics education. NABiS brings together leading universities in Sweden and Norway to provide high-quality training in taxonomy, systematics and biodiversity science, combining theoretical courses with practical field and lab components. As coordinator during the current period, I help ensure academic quality, facilitate collaboration among participating universities and support students navigating the programme’s courses and research opportunities.
