Bruno Bouchard est Professeur de mathématiques à l’Université Paris-Dauphine. Après des études d’économie et de finance, il a obtenu un doctorat en mathématiques appliquées et s’est spécialisé dans les aspects mathématiques de la gestion des risques. Il a dirigé la spécialité recherche de master Masef et dirige actuellement le diplôme de formation professionnelle DifiQ, spécialisés en finance quantitative. Il est membre du committee meeting de la Bachelier Finance Society et Editeur Associé des revues Finance and Stochastics, Mathematical Finance et de SIAM Journal on Financial Mathematics. Ses travaux couvrent un spectre large qui porte sur l’évaluation d’actif en marchés imparfaits, l’analyse des méthodes numériques probabilistes, le contrôle optimal stochastique et la modélisation de problématiques de gestion concrètes en collaboration avec l’industrie.
Il est actuellement Vice-Président du Conseil Scientifique en charge de la recherche.
