He currently leads the Centre on Information Technologies Development at University of Messina (CIAM), offering ICT services to public and private institutions. From 2006 to 2008 he acted as the technical director of the Project 901, aiming at creating a wireless/wired communication infrastructure inside the University of Messina to support new value added services (winner of the CISCO innovation award). He was also the responsible of two big Grid Projects (TriGrid VL and PI2S2) funded by the Sicilian Regional Government and by the MIUR, respectively. He is currently a member of the general assembly of CloudWave, an IP project funded from the EU to explore the deployment and management of new application services which adapt to the execution environment. He was also the main investigator of the Italian PRIN2008 project “Cloud@Home”, trying to combine cloud and volunteer computing. He is the scientific leader of the PON01 SIGMA project, that intends to develop cloud solutions to manage environmental multi-risk critical situations, integrating wireless and Cloud services. He is the scientific director of Inquadro s.r.l., a spin-off company whose main business is RFID and its application both in public and private sectors.
