The Association for Computing Machinery has recognized 42 of its members for their significant contributions to the development and application of computing in areas from data management and spoken-language processing to robotics and cryptography. 

The achievements of the 2015 ACM Fellows are fueling advances in computing that are driving the growth of the global digital economy.

While Ramanathan Guha was recognized for contributions to structured data representation and specification and their impact on the Web, Jayant R. Haritsa was cited for contributions to the theory and practice of data management systems.

Sriram Rajamani was cited for contributions to software analysis and defect detection, and Santosh Vempala was credited for his contributions to algorithms for convex sets and probability distributions.

The 2015 ACM Fellows have been cited for contributions to key computing fields including software research, data mining, computer graphics, computer and mobile systems, system security, multiprocessor and memory architecture design, and research in sensor networks.

ACM will formally recognize the 2015 ACM Fellows at its annual awards banquet in June 2016 in San Francisco, Calif.

Guha is a computer scientist at Google where he has worked since 2005. He graduated with a bachelor of technology in mechanical engineering from the Indian Institute of Technology Madras, master of science from the University of California, Berkeley, and Ph.D. from Stanford University.

Haritsa is a faculty member of SERC and CSA departments at Indian Institute of Science, Bangalore. He works on database systems and has won in 2009 the prestigious Shanti Swarup Bhatnagar Prize sponsored by CSIR, India and also the Infosys Prize for Engineering in 2014.

Rajamani is assistant managing director of Microsoft Research India. Prior to moving to the India lab, Sriram was most recently manager of the Software Productivity Tools group in Microsoft Research Redmond, Wash. Sriram has a Ph.D. in computer science from the University of California at Berkeley, a master’s of science in computer science from the University of Virginia, and a BE in computer science from Anna University College of Engineering, Guindy, in Chennai.

Vempala is a Distinguished Professor of Computer Science at the Georgia Institute of Technology. Vempala attended Carnegie Mellon University, where he received his Ph.D. in 1997. In 1997, he was awarded a Miller Fellowship at Berkeley. Subsequently, he was a professor at MIT in the Mathematics Department, until he moved to Georgia Tech in 2006.
