Professor Mateo Valero, born in 1952 (Alfamén, Zaragoza), obtained his Telecommunication Engineering Degree from the Technical University of Madrid (UPM) in 1974 and his Ph.D. in Telecommunications from the Technical University of Catalonia (UPC) in 1980. He has been teaching at UPC since 1974; since 1983 he has been a full professor at the Computer Architecture Department. He has also been a visiting professor at ENSIMAG, Grenoble (France) and at the University of California, Los Angeles (UCLA). He has been Chair of the Computer Architecture Department (1983-84; 1986-87; 1989-90 and 2001-2005) and the Dean of the Computer Engineering School (1984-85). His research is in the area of computer architecture, with special emphasis on high performance computers: processor organization, memory hierarchy, systolic array processors, interconnection networks, numerical algorithms, compilers and performance evaluation. Professor Valero has co-authored over 700 publications: over 500 in Conferences and the rest in Journals and book chapters. He was involved in the organization of more than 300 International Conferences as General Chair (11), including ICS95, ISCA98, ICS99 and PACT01, Steering Committee member (85), Program Chair (26) including ISCA06, Micro05, ICS07 and PACT04, Program Committee member (200), Invited Speaker (70), and Session Chair (61). He has given over 400 talks in conferences, universities and companies. He has been an associate editor of IEEE Transactions on Parallel and Distributed Systems, the IEEE Micro Journal and IEEE Computer Architecture Letters, the Journal of Parallel Programming Languages, as well as guest editing several special issues of the IEEE Transactions on Computers and Computer Magazine. In the area of his research he has participated in 35 European ESPRIT, RACE and COMETT projects (for some of these projects, he was instrumental in obtaining the participation of Spanish industry), 20 Spanish CICYT projects (similar to NSF projects) and 13 projects with American companies as IBM, Intel, HP and Microsoft.
