A Full Professor at the Information Engineering Department of the University of Pisa., he received a Laurea degree in Physics in March 1969 at the University of Pisa. From 1970 to 1994 he carried out research in networking at CNUCE, an institute of the Italian National Research Council ? CNR. In 1994 he left CNUCE with the position of Research Director since he was appointed full Professor in Computer Engineering at the University of Pisa. From 2005 to 2011 he was appointed part-time visiting professor at IMT (Institutions, Markets, Technologies), an Institute for Advanced Studies in Lucca, Italy. IMT is an open, competitive graduate school designed to best integrate research, education and innovation. He contributed to the organization of the school in terms of research and teaching. His main research interests are in the areas of Multi-hop Wireless Networks; Internet: Structure, Statistical Analysis and Dynamic Evolution. From 1973 to 1974 he worked on computer networks at the IBM Scientific Center in Cambridge, Massachusetts, USA. During that period he gained considerable experience in the field of architecture and protocols for computer networks, which at that time were in their very initial stages. He then exploited this knowledge by directing the design and implementation of RPCNET from 1973-1974 - the first Italian packet switching network, and one of the few European projects on packet switching networks, was designed and developed immediately after ARPANET was put into operation. In 1978-1982 RPCNET was tested by the Italian National Research Council (CNR) in its computing centers throughout Italy in order to evaluate the impact of a packet switching network on the CNR's processing capabilities. RPCNET helped create a culture in computer networks in Italy. He was involved with the STELLA (Satellite Transmission Experiment Linking Laboratories) project from1977-1983. This was the first European satellite broadcasting packet switching network. Its goal was to interconnect Local Area Networks (installed at European research laboratories) via ESA?s Orbit Test Satellite. Also involved in the project were: CERN, Rutherford Lab UK, Desy Lab, Germany, Joint Research Center - EURATOM, Italy, IAS/CNR Italy, Technical University of Graz, Austria, and Trinity College of Dublin, Ireland. He was one of the promoters of the Open Systems Interconnection (OSI), which led to the definition of OSI/RM within the ISO. The OSI/RM architecture exploited many ideas deriving from his research for RPCNET and STELLA. In 1982, he initiated OSIRIDE - a CNR project (Open Systems Interconnection Network Italian heterogeneous data), aimed at designing and activating a network of heterogeneous computers adhering to OSI/ISO international standards. OSIRIDE involved collaborations with BULL (Boston & Finix, USA), DIGITAL (Reading, UK), Hewlett-Packard (Grenoble, France), IBM (Sindelfingen, Germany) and Olivetti (Italy), Unisys (Salt Lake City, USA), TECSIEL SpA (Italy), IRI FINSIEL (Italy), and SIP (Italy). The brand name ?OSIRIDE? was patented. This project contributed significantly to the foundation of a software company in Pisa, named TECSIEL, which played a significant role in the implementation of the OSI protocols for the companies involved in the project. The Cooperation for Open Systems International, the largest worldwide OSI organization bringing together all manufacturers of computers, included OSIRIDE in the six most important projects worldwide. In the late 1970s, in cooperation with Robert Kahn and Vint Cerf (the inventors of TCP/IP, Turing Awards in 2004), he directed the initiative which led to the operation of the first Internet node in Italy (the third in Europe after the Norway and the UK). Specifically, towards the end of the 70s, Bob Kahn and Vint Cerf visited CNUCE, to discuss the extension of SATNET to Italy. At that time CNUCE was about to finish the STELLA project. This meant that CNUCE had the necessary competence for collaborating with the Internet/SATNET research community. The interconnection of the Italian section of Internet with the USA, UK and Norway was done via a SATNET gateway. In the mid-1980s the node was operative and the first TCP/IP experimentation started in Italy. From that period on a fruitful TCP/IP experimentation and discussions occurred between researchers from Pisa and from the USA. Other projects with which he was involved were: ESA SPACE DATA NETWORK (1988-1992) ESA (European Space Agency) Space Data Network project targeted at the design of an architecture and protocols able to use a communication system between ground stations and spacecraft, which at that time was at a design stage in Europe; MOSAICO (1998-2000) - He was head of the national project entitled ?Methodologies and Tools, System Design for High-Performance Distributed Applications? financed by the Italian Government and involving 20 Italian universities. EuQoS 2004-07. He was head of the Italian section of an IP project of the 6th framework program of the EU named EuQoS: End-to-end Quality of Service Support Over Heterogeneous Networks. EuQoS (IST-2-004503-IP) was funded by the European Union 6th Framework Program; NADIR (2007-2009) - He was head of NADIR "Design and Performance Evaluation of Distributed Algorithms and Protocols for Mesh Networks with Quality of Service". NADIR was funded by the Italian Ministry of Education, University and Research (MIUR). WIMAX/NOKIA (2001-2008) - He worked in tight cooperation with the Nokia Research Center in Helsinki in a collaboration to: i) design scheduling algorithms for radio resource allocation both on the base station and user terminals; ii) evaluate the performance of the designed algorithms via simulation. The collaboration led to several patents; LTE AND BEYOND/TELECOM ITALIA (2006-2011) - Since 2006 he began working with the research laboratory of Telecom Italia located in Turin in the framework of a cooperation targeted at designing scheduling algorithms for radio resource allocation on the base station, relay nodes and user terminals. The collaboration has already led to several patents; and CONGAS (began October 2012) - He is the head of the University of Pisa Research Unit of an FET Proactive (Objective ICT-2011.9.7) project named CONGAS: Dynamics and Coevolution in Multi Level Strategic Interaction Games. CONGAS will last three years and is funded by the European Union 7th Framework Program. Committee Memberships and Chairmanships he holds are: 1976-1978: Italian delegate, on behalf of the Ministry for Coordination of Scientific and Technological groups TAG (Technical Aspects Group) and Host Computers of the DG XIII of the European Economic Community. These groups operated within EURONET, the first European public packet switching network, which was activated in 1978; 1976-1977: Chairman of the COSADOC (Communications Satellite Ad Hoc Working Group), of the European Space Agency; 1981-1984: Chairman of the Satellite Group, established within the European project COST 11a, which studied the relationship between the technology offered by satellites and the reference mode OSI (Open Systems Interconnection) of the ISO (OSI/RM); 1982-1983: member of the board of an Italian research program in telematics and office automation at the Ministry for Coordination of Scientific and Technological Research (MURST); 1984-1987: member of the Technical Consultancy Group of the ESPRIT Information Exchange System of the EEC; General Chairman of the 1992 IEEE Workshop on Metropolitan Area Networks (Taormina - Italy); General Chairman of the European Wireless 2002 conference (Florence - Italy); Co-founder and General Chairman of the ValueTools 2006 conference (Pisa - Italy); General Chairman of the European Wireless 2010 conference (Lucca - Italy); Since 2009 he is chairman of the Italian Group on Quantitative Methods in Informatics (Informatica Quantitativa - www.infq.it); and Chairman of the Italian GII Doctoral School 2012 (http://gii-infq.lab.imtlucca.it) which was held in Lucca from June 25th to July 6th, 2012. Among the publications he has authored/edited, or co-authored/edited are: IEEE Journal on Selected Areas in Communications, special issue entitled Analysis and Synthesis of MAC Protocols, Volume 18, Number 9, September 2000 with John O.
