  • The EXPRESS/SOS 2021 website is now on-line!

  • Big news!! I will be the PC co-chair for EXPRESS/SOS 2021 and EXPRESS/SOS 2022.

  • Our paper On the Axiomatisability of Parallel Composition: A Journey in the Spectrum was shortlisted for the Best Paper Award at CONCUR 2020.

  • All the updates on the OPEL project can be found here.

  • For the papers, I'll try to keep the list of publications updated and to add all the preprints. Of course, please refer to the DOI for the official publisher version of all papers (you can also find them on my DBLP page). Please, do not hesitate to contact me, in case you need a missing preprint. Papers available for download can be also found on my ResearchGate page,

Research Interests

My research activity is mainly focused on formal methods for concurrent systems. In particular, I am interested in:

  • Metric and approximate semantics reasoning on probabilistic languages

  • Equational logic of processes

  • Logical characterizations for probabilistic languages

  • Formal methods applied to biological systems
