I have an on-going interest in studying the physiological mechanisms that allow fishes to cope with their environments. More specifically, I’m interested on their amazing capability to reproduce, develop and thrive in different situations.

MARBEC MARine Biodiversity, Exploitation and Conservation, est une unité de recherche qui regroupe des personnels de 4 organismes : l’IRD, l’Ifremer, l’UM et le CNRS. Son objectif est l’étude de la biodiversité marine des écosystèmes lagunaires, côtiers et hauturiers à différents niveaux d’intégration, depuis les aspects moléculaires, individuels, populationnels et communautaires, et des usages de cette biodiversité par l’Homme.
