ACM has recognized 20 of its members for their contributions in computer science and information technology. The new ACM Fellows, from leading universities, corporations and research labs throughout the world, made significant advances in both the theoretical and practical aspects of computing that are having lasting effects on the lives of citizens throughout the world. Reflecting a broad range of their expertise in computing, the 2004 ACM Fellows were cited for contributions to error-correcting codes and mobile code security; query optimization and processing in database systems; and advances in distributed computing. Other Fellows were recognized for their work in high-performance computing systems, computing technologies for individuals with disabilities, and Internet domain and email protocols. Still others were cited for their inventions in processor architecture and design, and for leadership in the computer science community. "These ACM members have advanced the computing discipline and underscored its increasingly critical role in our global, communications-rich society," said John White, CEO of ACM. "Through their outstanding contributions and their exemplary service, these members have provided inspiration, innovation and leadership to the computing and IT community," he said. The new ACM Fellows join a distinguished list of colleagues to whom ACM and its members look for guidance and leadership in computing and information technology. Initiated in 1993, the Fellows program celebrates the exceptional contributions of the leading members in the computing field. These individuals have helped to enlighten researchers, developers, practitioners and end-users of information technology throughout the world. ACM's newest Fellows reflect the makeup of the association's diverse membership roster, with representation from men and women, from universities and corporations, and from within and outside the U.S. ACM will formally recognize the new Fellows at its annual Awards Banquet in June 2005.
