On behalf of the IEEE Computer Society and the Editorial Board of this journal, I wish to thank the following people, who have retired from the board, for their service: Pascale Charpin, Mark Crovella, Kemal Ebciouglu, Matthew Farrens, Laxmi P. Gewali, Anwar Hasan, David Kaeli, Paolo Montuschi, Irith Pomeranz, Karsten Schwan, H.J. Siegel, Anand Sivasubramaniam, Gurindar Sohi, Per Stenstrom, Ioannis Tollis, Peter Varman, Uzi Vishkin, and Scott Wills. It has been an honor and a pleasure working with them. I would like to take this opportunity to thank them for the selfless service they have given these transactions during all these years. It is only with the work of dedicated volunteers such as these that we have been able to continue offering the scientific community the high quality papers, which remain the trademark of the IEEE Transactions on Computers.
At the same time, I am pleased to welcome Jean-Claude Bajard, Todd Brun, Frank Dehne, Michel Dubois, Antonio M. González, Cecilia Metra, and Assaf Schuster, who are now joining the Editorial Board. Their biographical sketches highlight their accomplishments and areas of expertise. They are all internationally recognized in their fields and the journal is fortunate indeed to have these outstanding researchers as members of the Editorial Board.
Dr. Bajard will help us handle papers in several important areas, including number systems and computer arithmetic. Dr. Brun will help us handle papers in several important areas, including quantum computation and quantum information theory (which include quantum cryptography, quantum error correction, quantum communications, entanglement quantification, and other topics), and simulation of quantum systems. Dr. Dehne will help us handle papers in several important areas, including algorithms and data structures, practical implementations and related issues, parallel algorithms, data warehousing, bioinformatics, and computational geometry. Dr. Dubois will help us handle papers in several important areas, including computer architecture and parallel processing, with a focus on multiprocessor architecture, performance and algorithms. Dr. González will help us handle papers in several important areas, including processor microarchitecture, and code generation and optimization. Dr. Metra will help us handle papers in several important areas, including testing methods and tools, fault tolerance, reliability, security, and testability. Dr. Schuster will help us handle papers in several important areas, including large-scale distributed systems, distributed data mining and model checking, and security aspects of distributed systems.

His research interests are in computer arithmetic, in particular, number representations, elementary functions, multiprecision computing, modular arithmetic, finite fields, operators for cryptography, VLSI algorithms. His main international collaborations are with Milos Ercegovac (UCLA), Graham Jullien (ATIPS), and Peter Kornerup (Odense). He has served on the program committees of the IEEE Symposia on Computer Arithmetic and served as coprogram chair for this symposium in 2003. He is also serving as a coeditor, with Michael Schulte, of a special issue of the IEEE Transactions on Computers (to appear in 2005). He is a member of the IEEE Computer Society.

Todd Brun received the AB degree in physics from Harvard University in 1989 and the MS and PhD degrees in physics in 1991 and 1994 from the California Institute of Technology.

From 2000 to 2003, he was a member of the School of Natural Sciences at the Institute for Advanced Study in Princeton. Since 2003, he has been a faculty member in the Department of Electrical Engineering at the University of Southern California, where he is an assistant professor. His research is in quantum computation and quantum information processing.

Frank Dehne received the MCS degree (Dipl. Inform.) from the TechnicalUniversity of Aachen, Germany, in 1983 and the PhD degree (Dr. Rer. Nat.) from theUniversity of Würzburg, Germany, in 1986. In 1986, he joined the School ofComputer Science at Carleton University in Ottawa, Canada, as an assistant professor. He was appointed an associate professor and professor of computer science in 1990 and 1997, respectively. From 2000 to 2003, he served as the director of the School of Computer Science. In 2004, he was appointed a professor of information technology at Griffith University in Brisbane, Australia. His current research interests are in the general area of algorithms and practical implementations, in particular parallel computing, coarse-grained parallel algorithms, computational geometry, parallel data warehousing and OLAP, and parallel bioinformatics. He is particularly interested in the interrelationship between the theoretical analysis of algorithms and the performance observed when these algorithms are implemented. He is a senior member of the IEEE, vice-chair of the IEEETechnical Committee on Parallel Processing, and a member of the Steering Committee of the ACM Symposium on Parallel Algorithms and Architectures.He is a founding co-investigator of HPCVL ( www.hpcvl.org), a largeregional parallel computing center with more than $40M funding fromgovernment and industry.
