Robert M. Gray is the Alcatel-Lucent Technologies Professor of Communications and Networking in the School of Engineering, Emeritus, and Professor of Electrical Engineering, Emeritus, at Stanford University. He is a Fellow of the IEEE and the Institute for Mathematical Statistics and he was a 1981--82 Fellow of the John Simon Guggenheim Foundation. His professional awards include an Education Award, Meritorious Service Award, Technical Achievement Award, and Society award from the IEEE Signal Processing Society, a Golden Jubilee Award for Technological Innovation and the Claude E. Shannon Award from the IEEE Information Theory Society, and the Jack S. Kilby Signal Processing Medal and Centennial and Third Millennium Medals from the IEEE. He received a Presidential Award for Excellence in Science, Mathematics and Engineering Mentoring (PAESMEM). He is a member of the National Academy of Engineering. He retired from Stanford in April 2013 and is currently a Research Professor at Boston University.
My current research falls in the intersection of Shannon information theory and signal processing. In particular, I am interested in the theory and design of block codes and sliding-block (or stationary or time-invariant) codes for data compression and their relation to each other. Block codes are far better understood and more widely used, but their lack of stationarity causes difficulties in theory and artifacts in practice. Very little is known about the design of good sliding-block codes, but the problem is known to be equivalent to the design of entropy-constrained simulators of complex random processes. I also do research in the history of information theory and signal processing, especially in the development of speech processing systems and real time signal processing.
