Current research
Alain's research interests are in continuous optimization, with special focus on bilevel optimization and its applications to transportation (toll setting, network design, demand estimation), data analysis, forecasting, trust topology, and phase retrieval.
In addition to research involving machine learning problems with a hierarchical structure and applications of optimization (pricing, network design, medicine, etc.), he has developed optimality conditions and stability/sensitivity analysis results for such problems and is currently developing numerical algorithms that can capture the optimistic and pessimistic feature of bilevel optimization problems.
