Frédéric Quesnel is a professor of operations research at the Analytics, Operations, and Information Technology department of the École des Sciences de la Gestion de l'Université du Québec à Montréal (ESG-UQAM). He received a PhD in Applied Mathematics from Polytechnique Montréal. His work focuses on solving large-scale combinatorial problems, mainly for airline applications. He also works on developing primal algorithms for integer programming. Recently Frédéric started exploring new uses of machine learning to improve the branch-and-price algorithms used to solve such problems.
