Fabrizio Lombardi graduated in 1977 from the University of Essex (UK) with a B.Sc. (Hons.) in Electronic Engineering. In 1977 he joined the Microwave Research Unit at University College London, where he received the Master in Microwaves and Modern Optics (1978), the Diploma in Microwave Engineering (1978) and the Ph. D. from the University of London (1982). He is currently the holder of the International Test Conference (ITC) Endowed Chair at Northeastern University, Boston. Currently, Dr. Lombardi is the 2022-2023 President; of the IEEE Nanotechnology Council (NTC); in 2021 he was 2nd VP of the IEEE Computer Society (CS). He is also a member of the IEEE Publication Services and Products Board (PSPB) (2019-2023). He was the VP of Publications of the IEEE CS (2019-2020) and the NTC (2020). He has been appointed on Executive Boards of many non-profit organizations (such as Computing-in-the-Core, now code.org the non-partisan advocacy coalition for K-12 Computer Science education) as well as the Computer Society (as an elected two-term member of its Board of Governors (2012-2017)) and the IEEE (as an appointed member of the Future Directions Committee (2014-2017)).
In the past, Dr. Lombardi has been a two 2-year term Editor-in-Chief (2007-2010), Associate Editor-in-Chief (2000-2006) and Associate Editor (1996-2000) of the IEEE Transactions on Computers, the inaugural two-term Editor-in-Chief of the IEEE Transactions on Emerging Topics in Computing (2013-2017); Editor-in-Chief of the IEEE Transactions on Nanotechnology (2014-2019) as well as member of the Editorial Boards of the ACM Journal of Emerging Technologies in Computing Systems, the IEEE Design & Test Magazine and IEEE Transactions on CAD of ICAS. Dr. Lombardi has been twice a Distinguished Visitor of the IEEE Computer Society (1990-1993 and 2001-2004).
Dr. Lombardi is a Fellow of the IEEE for ”contributions to testing and fault tolerance of digital systems”. He was the recipient of the 2011 Meritorious Service Award and elevated to Golden Core membership in the same year by the IEEE CS; he was the Chair of the 2016 and 2017 IEEE CS Fellow Evaluation Committee. He has been awarded the 2019 NTC Distinguished Service Award, the 2019 “Spirit of the CS” Award and the 2021 T Michael Elliott Distinguished Service Certificate from the CS. He has received many professional awards: the Visiting Fellowship at the British Columbia Advanced System Institute, University of Victoria, Canada (1988), twice the Texas Experimental Engineering Station Research Fellowship (1991-1992, 1997-1998) the Halliburton Professorship (1995), the Outstanding Engineering Research Award at Northeastern University (2004) and an International Research Award from the Ministry of Science and Education of Japan (1993-1999). Dr. Lombardi was the recipient of the 1985/86 Research Initiation Award from the IEEE/Engineering Foundation and a Silver Quill Award from Motorola-Austin (1996). Together with his students, his manuscripts have been selected for the best paper awards at technical events/meeting such as IEEE DFT and IEEE/ACM Nanoarch.
Dr. Lombardi has been involved in organizing many international symposia, conferences and workshops sponsored by professional organizations as well as guest editor of Special Issues in archival journals and magazines.
