Research Interest
My research work is mainly concerned with the study of bilevel programs, optimization problems with variational constraints, for which I proposed both exact algorithms and powerful heuristic procedures based on the particular structures of the problem.
In particular I have studied pricing problems (revenue management ) on networks.
Bilevel pricing problems (Stackelbeg games) allow to integrate explicitedly the behaviour of the consumer inside the revenue maximization objective of a company. From an economical point of view these models are offer-demand equilibrium models where the demand function results from the solution of a mathematical program.
Applications in the transportation, telecommunication and energy field are under study.
Since 2015, I am the Team Leader of the INRIA Team INOCS: Integrated optimization with complex structure.
