My research activity mainly deals with fault and attack tolerance in self-organized distributed systems and networks, i.e. systems that must operate without human intervention. I am particularly interested in self-stabilization and its variants, which permit a protocol to recover correct operation after catastrophic transient failures hit the entire system. Such an approach permits both to mathematically prove the fault and attack tolerance properties that are obtained, but also can limit the impact on both memory and time with respect to classical approaches that can only operate on completely reliable distributed systems and networks.
