Special fields
Molecular systematics including biogeography and evolutionary processes at low taxonomic levels, in particular in arctic and alpine regions. Recent projects focus on speciation genetics, comparative phylogeographic and phylogenetic analyses, DNA barcoding, polyploid evolution, and long-distance dispersal.
Ongoing and planned research projects
MolBar: The molecular basis of postzygotic hybridization barriers in plants
SpeciationClock - How fast does the "speciation clock" tick in selfing versus outcrossing lineages?
