Presentation

Je suis chercheur à l'INRAE (unité PEGASE : Physiologie, Environnement et Génétique pour l'Animal et les Systèmes d'Élevage) à Saint-Gilles (Ille-et-Vilaine, France). **J'étudie le déterminisme génétique de l'allocation des ressources chez les femelles de rente, en particulier chez la poule pondeuse**. Auparavant, j'ai étudié les compromis entre les fonctions de reproduction, de production et de gestion des réserves corporelles chez la vache laitière, en tant que doctorant à l'INRAE (2013-2016) et ensuite comme ingénieur de recherche au sein du Groupe ESA à Angers (2017-2018).
