Titulaire d’un doctorat et d’un Habilitation à Diriger des Recherches de l’Université de Bordeaux, j’occupe actuellement un poste de Professeur en Statistiques à Bordeaux Sciences Agro. Parallèlement, je mène une activité de recherche au sein du Groupe Signal et Image du Laboratoire IMS où j’anime la thématique MOTIVE (Modèles, Textures, Images, VolumEs).
Ma problématique de recherche porte essentiellement sur l’analyse et la synthèse d’images et de volumes texturés. Elle trouve des applications en caractérisation de matériaux et en proxidétection agricole.
