Research interests

I have relatively diverse research interests in evolutionary biology with topics ranging from speciation and reproductive isolation, invasion processes, behavior genetics to host-pathogen co-evolution. Research approaches span genome and transcriptome analyses as well as the use of "classical" molecular markers and morphological data, but we may also set up specific experiments in the laboratory and perform extensive observations in the field. Study organisms are most often rodents of the Microtus and Myodes genus and their more or less faithful parasites, but also other vertebrates and invertebrates. My recent publications below give a flavor of my research interests and study organisms.
