Presentation

Je suis Professeur Associé à CentraleSupélec et membre du L2S et de l'équipe Inria-DISCO, Gif-sur-Yvette, France. J'ai soutenu mà thèse en 2010 au groupe MAC (Méthodes et Algorithmes en Commande) du LAAS/CNRS à Toulouse, avec un financement du programme Alban. Pendant ma thèse j'ai développé des méthodes basées sur l'optimisation convexe, en particulier sur des méthodes somme-de-carrées pour l'analyse en stabilité et projet de lois de commande pour des systèmes non-linéaires avec contraintes. De 2010 à 2012, j'ai réalisé un Post-doc ( Assegnista di Ricerca) dans le Dipartimento di Ingegneria di Sistemi e Produzione à l'université de Rome, Tor Vergata. De 2013 à 2015, j'ai réalisé un Post-doc (Post-Doctoral Research Assistant) dans le Control Group, Engineering Department, University of Oxford, Oxford, UK. De 2013 à 2015, j'ai été Fulford Junior Research Fellow au Somerville College, University of Oxford, Oxford, UK.
