Mes activités de recherche sont au cœur du domaine d'optimisation combinatoire et d'intelligence artificielle. Elles portent principalement sur:
 Conception d'algorithmes efficaces pour la résolution de problèmes d'optimisation combinatoire.
Développement de modèles mathématiques pour les systèmes complexes.
Développement d'algorithmes à base d'heuristiques, méta-heuristiques, math-heuristiques et méthodes exactes.
Fournir des décisions managériales efficaces dans plusieurs domaines tels que les systèmes de transport, les systèmes de chargement, la logistique, le Cloud Computing, etc.
Parallélisation des méthodes approchées sous GPU "Graphics Processing Unit".
Les résultats de mes recherches, théoriques et pratiques, ont été publiés dans des revues scientifiques internationales à savoir :
