Research
My research aims at identifying the genomic basis of adaptive traits. It focuses on the systematics and evolution 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 basis of two traits : first, an apparent case of sexual color mimicry, which has independently evolved in more than 20 species, and second, a recurrent specialization on a toxic fruit in an island population of a generalist species.
Keywords
Population genomics, functional genetics, sexual selection, ecological speciation, Drosophila evolution.
