I am interested in the evolution of animals in the deep-sea, and for my PhD thesis I am working on animals living at hydrothermal vents and cognate habitats (cold seeps and organic falls). 

I am mainly working on polychaete worms (phylum Annelida) in the families Siboglinidae and Ampharetidae.

Questions I want to answer are: Are the species found here closer related to species in the Atlantic or the Pacific? How does barriers affect speciation in the deep-sea? How does the hydrothermal vent fauna relate to that found on cold seeps? And when did the speciation into the Arctic system happen? 

I also want to explore the global biogeographic position of the arctic vent fields using multivariate statistics.

I assist on several courses, both on bachelor and master level:

BIO101 and BIO102 (Organism biology 1 and 2)

BI0211 (Marine floristics og faunistics)

BIO300 (Biological data analysis og research design)
