Mes recherches s’intéressent aux processus écologiques et évolutifs qui façonnent diversité et structure génétiques des populations naturelles d’espèces marines aux caractéristiques originales (e.g. grande taille de population, forte fécondité, phase larvaire longévive). Pour aborder cela, j’utilise les concepts et les méthodes d’analyse issus de la génétique des populations et les applique aux données de polymorphisme produites à l’aide des technologies de séquençage haut-débit (e.g. SNPs).
Ces approches m'ont notamment permis d’estimer la diversité génétique, la taille efficace ou le fardeau de consanguinité des populations naturelles d'invertébrés marins, mais également de délimiter la biodiversité cryptique chez des espèces à valeur commerciale (e.g. Holothuria scaba) ou d’intérêt d’un point de vue de la conservation (e.g. Hippocampus guttulatus, Gongolaria barbata en Europe).
