Guy Blelloch, professor of computer science, and Robert Kraut, the Herbert A. Simon Professor of Human-Computer Interaction, are among 46 leading computer scientists named 2011 Fellows by the Association for Computing Machinery.

The ACM cited Kraut for his contributions to human-computer interaction and Blelloch for his work in parallel computing.

ACM will formally recognize the 2011 Fellows at its annual Awards Banquet on June 16, 2012, in San Francisco, CA. Additional information about the ACM 2011 Fellows, the awards event, as well as previous ACM Fellows and award winners is available at www.acm.org/awards.

"These women and men, who are some of the leading thinkers and practitioners in computer science and engineering, are changing how the world lives and works," said ACM President Alain Chesnais. "They have mastered the tools of computing and computer science to address the many significant challenges that confront populations across the globe. These international luminaries are responsible for solutions that are transforming our society for the better- in healthcare, communications, cybersecurity, robotics, commerce, industry, and entertainment."
