Scientific Interest

Genetics of speciation, adaptive radiation and adaptation to environmental change in fish (threespine stickleback Gasterosteus spp., East African cichlids Haplochromini) and birds (e.g. large white-headed gulls Larus spp.). Reconstructing the evolutionary history from genomes. Investigating genetic diversity, an often overlooked component of biodiversity.
