News June 2017: Our paper "A generic transformation for optimal repair bandwidth and rebuilding access in MDS codes" is one of the three winners of the 2017 IEEE Jack Keil Wolf ISIT Student Paper Award! (More details here) Jie completed the majority of the work reported in this paper while with UTK on a one-year CSC fellowship. We would like to thank the China Scholarship Council for the generous support which enabled this work. Congratulations, Jie!

SCITL: Solutions of Computed Information-Theoretic Limits
We recently developed a computational approach to identify and prove information-theoretical limits, whose potential is yet to be fully explored. Here is a collection of results on several data storage and communication problems. Unsolicited contributions are welcome. If you have a burning question and think this approach may be helpful, please contact me.
To see the results on the SCITL page.

Some Fun Facts
Erdos Number = 3
I had the previlige of working with N.J.A. Sloane at AT&T Labs.
Number of Coauthors Who Are Shannon Awardees = 5
Perhaps as an alternative definition of the "Shannon Number"?
