Intérêts de recherche et expertise

Mes intérêts de recherche portent sur la conservation de la biodiversité d’un point de vue scientifique, éthique et politique.

Je coordonne l’étude à long terme des flamants roses Phoenicopterus roseus et des Goélands railleurs Chroicocephalus genei. Nous nous attachons à mieux comprendre la biologie de ces espèces en utilisant les outils de dynamique des populations, de génétique et d’écologie comportementale dans une approche intégrée.
