Interests "Photo of me"

Formal methods, logics, protocol verification and model checking.

Reverse bio

Starting February 2017, I am Assistant Professor in Computer Security at the IT-University of Copenhagen. Previously, I worked as a Postdoc in Carsten Shürmann’s group at the IT-University of Copenhagen, working on the Meta-CLF project. I obtained my Ph.D. at the Technical University of Denmark, under supervision of Flemming Nielson and Hanne Riis Nielson, working on formal methods, security protocol verification and model checking, and before that I did my B.Sc. and M.Sc. at the University of Padova, Italy, graduating under supervision of Paolo Baldan.

Current events



AIF-Omega is an abstraction based verification tool for security protocols where participants have state that is beyond a single session.

SetPi (Now being merged with AIF-Omega) is an extension of the Applied Pi-calculus with support for persistent state, expressible in terms of names that can grow and shrink over time.

CPNunf is an unfolder for contextual Petri nets, an extension of this formalism with semantics to support concurrent read access to shared resources
