My research focuses on the systematics and evolutionary genetics of flies in the family Drosophilidae. Drosophila melanogaster is undoubtedly a genetics star, but our understanding of the morphological and ecological diversity of non-melanogaster drosophilids remains nebulous. I attempt to establish a comprehensive phylogenetic classification of the family based on molecular and morphological data. I also combine population and functional genomics approaches to unravel the genetic basis of diverging phenotypes, such as female-limited color dimorphism, genital coevolution, host plant specialization and insular speciation.
