Dario Benedetti

Research Interests

My main area of research is quantum gravity. More specifically I work on the asymptotic safety scenario, using functional renormalization group methods, and on causal dynamical triangulations, using numerical and analytical methods to study the continuum limit of these models. I also work on some models of non-commutative geometry with quantum group symmetry, which have a strong motivation in their potential for quantum gravity phenomenology.
