Research Interests

I am primarily interested in the population biology of conflict and cooperation, i.e. in the evolutionary ecology (a.o. sex allocation and mating systems) and population genetics of insect societies including their social parasites and in the co-evolutionary study of mutualisms. Important model systems are the fungus-growing ants and termites and their symbionts, Maculinea butterflies and their Myrmica host ants, and Lasius and Formica ants. Additional projects have focused on the population- and breeding structure of vertebrate species in Denmark and insects in Greenland. Most studies involve some combination of field studies, experiments and analysis of DNA markers. My group is increasingly involved in biodiversity and conservation studies and is supported by the Danish Natural Science Research Council (Centre of Social Evolution and Symbiosis), an EU Research-training network (INSECTS) that I coordinate, and various other EU network grants and individual Marie Curie fellowships.
