Biographie

Julien Grand-Clément est un professeur assistant en systèmes d'information et gestion des opérations à HEC Paris. Il possède un doctorat de l'Université de Columbia (NY, USA) et un master de l'Ecole polytechnique (Paris). Sa recherche se concentre sur l'automatisation des décisions médicales et les algorithmes d'optimisation robuste. Ses dernières collaborations concernent la répartition des lits en salles de soins intensifs dans des hôpitaux californiens et le triage des respirateurs dans des hôpitaux new-yorkais. Ses articles de recherche ont paru dans des journaux académiques, ainsi que dans des conférences médicales et d'intelligence artificielle.
