I am currently an Associate Professor the at the L2S, CentraleSupelec, Gif-sur-Yvette, France. I completed my PhD in 2010 at LAAS/CNRS at Toulouse, funded by the Programme Alban. My research was carried out under the supervision of DR. Sophie Tarbouriech and Prof. Germain Garcia in the group MAC (Méthodes et Algorithmes en Commande). My thesis focused on developing methods based on convex optimization and polynomial programming for the stability analysis and controller synthesis of polynomial systems and systems with input constraints. From 2010 to 2012 I was Assegnista di Ricerca' with the Dipartimento di Ingegneria di Sistemi e Produzione at the University of Rome Tor Vergata under the supervision of Prof. Luca Zaccarian and Prof. Sergio Galeani. From 2013 to 2015 I was Post-Doctoral Research Assistant at the Control Group, Engineering Department, University of Oxford, Oxford, UK, under the supervision of Prof. Antonis Papachristodoulou. From 2013 to 2015 I was a Fulford Junior Research Fellow at Somerville College, University of Oxford, Oxford, UK.
