I received my Ph.D. in the Pure and Applied Logic Program from Carnegie Mellon University in 2000. My adviser was Frank Pfenning. I moved to Leicester and then to Edinburgh, where I worked as a research scientist on the MRG and Mobius project. I'm now (and will be) an associate professor at DI, University of Milan, Italy.
