Research

My main research focus is on speciation and evolutionary genomics. Why do some taxa rapidly generate new species, whereas others remain species-poor? I am particularly interested in the role of hybridisation (interbreeding) in rapid speciation and adaptation. My study systems include Neotropical butterflies and African cichlid fishes.
