Marouane Felloussi


I am a 3rd year Ph.D. student at LIMOS Research Lab and Mines St-Etienne, and I am grateful to be advised by Xavier Delorme and Paolo Gianessi.

My research interests lie in combinatorial optimization and mixed-integer programming, with a particular focus on decomposition methods. Application areas include combinatorial optimization problems in production systems, such as scheduling and packing. I am also broadly interested in graph theory, and more recently, formal proof verification.
