Présentation

Après un doctorat sur les propriétés électroniques et la stabilité des quasicristaux (1990 ; ENS Paris & Univ. P. & M. Curie), j’ai passé deux ans aux AT&T Bell Labs (NJ, USA) où j’ai travaillé sur le magnétisme et la supraconductivité à haute température critique. J’ai également commencé à m’intéresser à la physique statistique hors équilibre, qui est depuis devenue mon principal domaine de recherche au Laboratoire de Physique Théorique de Toulouse : processus stochastiques et leurs applications physiques, séparation de phases et systèmes retournant à l’équilibre, physique de la société et biologie comportementale…

En particulier, depuis 2014, je me consacre presque exclusivement à l’étude des phénomènes collectifs (mouvements, prise de décision…) dans les groupes animaux et humains, développant une collaboration fructueuse avec Guy Theraulaz et son groupe au CRCA/CBI à Toulouse (voir l’onglet Thèmes de recherche sur ma page web). Je conçois les expériences avec Guy Theraulaz, je les réalise sur les humains (mais pas sur les poissons), je traite et analyse les données, et je développe des modèles comportementaux inspirés des outils de la physique statistique.

Outre mon activité de recherche pure, je consacre un temps important à l’enseignement et à la vulgarisation scientifique (voir l’onglet Vulgarisation sur ma page web).
