### Research interests

Main research interests concern the formal analysis of processes involving probability and nondeterminism. In particular current research topics are formal analysis of properties of the Segala’s Probabilistic Automata model with respect to other probabilistic models and in developing conservative extensions of such model in order to formally define and study properties of real systems using an uniform approach.

I am also interested in the study of cryptographic protocols for the development of a framework based on probabilistic automata in order to provide a rigorous mathematical background that justifies such analyses as well as the management of nondeterminism in order to avoid undesirable behaviors induced by the resolution of nondeterminism.

Probability is a key ingredient in the definition of security of cryptographic primitives while nondeterminism arises from the interaction of several parties involved in a protocol specification as well as from the adversary that tries to attack the protocol.
