My research interests are mainly focused on the applications of DNA from environmental samples, both in freshwater and marine environments as well as several other sources such as terrestrial sediments, human coprolites and leech gut contents. I also work with topics such as animal evolution, ecology and conservation.

Furthermore, I am an active amateur entomologist. My main interest is beetles, especially distribution, ecology and conservation of Danish Coleoptera.

I have a great deal of experience in traditional ecological fieldwork covering national monitoring of endangered insect species on the EU Habitat Directive and has contributed to international and national redlisting of threatened species.

Current research

Environmental DNA from aquatic samples

We work with detection and quantification of selected animal species through DNA in small water samples from both freshwater and marine habitats. Several different animal groups – amphibians, fish, mammals, birds, insects and crustaceans – have shown detectable using eDNA from freshwater samples. In seawater samples we have been working with fish and whales.

DNA from old insects in museum collections

We apply special non-destructive DNA extraction protocols to retrieve DNA from old museum insect specimens. The project investigates the possibilities of retrieving mtDNA from various insect specimens ranging in age back to 200 years.
