I am currently at the Engineer Faculty of Università di Roma Tor Vergata, where I m teaching Operations Research and Game Theory and Network Design. Research Topics My main area research is that of Combinatorial Otpimization. I am particurarly interested in: 1) Network Design problems, with a particular emphasis on issues of resiliency and robustness; 2) Polyhedral Combinatorics, with a focus on the independent set problem, from both the polyhedral and the algorithmic point of view.
