Mots clés population genetics/genomics micro-evolutionary drivers marine species demographic history

My research interest mainly focuses on understanding how act (and interact) micro-evolutionary drivers in marine species displaying atypical demographic characteristics using molecular markers. During my PhD, I specifically aimed to understand the role of selection and genetic drift drivers in the invasive marine gastropod Crepidula fornicata. In a first post-doctoral position, I reconstructed the evolutionary history of several pipefish and the role of sexual selection in the maintenance of reproductive isolation in these apparently panmictic nearshore inhabitants. My interests still aroused on the same themes, I’m starting a post-doc at ISEM focusing on the genetic differentiation along Mediterranean and Atlantic coasts in the long-snouted seahorse, Hippocampus guttulatus
