I am from Rome, where I studied at the Sapienza University of Rome, advised by Pierluigi Crescenzi. I have also been a postdoc at MIT (with theTheory of Computing Group) and at DIMACS, an assistant professor at Columbia University and a professor at Stanford.
I am interested in Theoretical Computer Science.
