I am a full professor at University of Catania.

Before joining the University of Catania as a faculty, I used to be a full time researcher at the French CNRS. In particular, I was part of the Crypto Team, at the Laboratoire d’Informatique de l’Ecole Normale Supérieure, in Paris for five years (1 as a postdoc and 4 as a CNRS researcher).

I did both my graduate and my undergraduate studies at the University of Catania.
During my Ph.D.  I spent more than two years in New York City, where I was affiliated with the Computer Science Department of Columbia University and with the Security Group of the IBM T.J. Watson Research Center.
My advisor was Rosario Gennaro from IBM.


Over the last fifteen years, my research activity has been concerned with cryptography and, in particular, to reducing the gap between theory and practice in cryptography. My research agenda mostly concentrates on foundational issues inspired by practical needs and on questions related to the realizations of secure and efficient cryptographic constructions addressing such needs. Such topics include, for example, password based cryptography, electronic voting and, in particular, cryptographic primitives with special properties (e.g. homomorphic signatures and MACs, searchable encryption).

In the early stages of my career I was also interested in the theory of machine learning.
