Chercheur en Génétique Animale

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).
