Prof. Ning Cai / 蔡宁 教授 (IEEE Fellow)

Major: EES


  • Network coding
  • Classical information theory
  • Quantum information theory


Ning Cai received the B.S. degree in mathematics from the Normal College of Beijing, Beijing, China in 1982; the M.S. degree in mathematics from the Institute of System Science, Academia Sinica, Beijing, China, in 1984; and the Dr. degree in mathematics from the University of Bielefeld, Bielefeld, Germany, in 1988. During 1989-2005 he worked in the University of Bielefeld, Germany, the National University of Singapore, Singapore and the Chinese University of Hong Kong. Form 2006 to 2016 he was a distinguished professor Xidian University, China. He joined ShanghaiTech university in 2016. As a visiting professor, he visited the Technical University Of Munich, the Chinese University of Hong Kong, the University of Bielefeld , the University of South Australia, the Norwegian University of Science and Technology, and the University of Waterloo. Dr. Cai served as a IEEE IT Society Awards Committee member in 2008 and 2009, and a guest editor of joint Special Issue of IEEE Trans. on InformationTheory and IEEE/ACM Trans. on Networking, on “Networking and Information Theory”, 2006. He has served on the committees of a number of information theorysymposiums and workshops. Dr. Cai is a recipient of the 2005 IEEE Information Theory Society Paper Award for the paper “Linear network coding” and of the 2016 IEEE Eric. E. Sumner Award for “pioneering contributions to the field of network coding”, both with S-Y. R. Li and R. W. Yeung. He is a IEEE fellow. His research interests include network coding and classical and quantum information theory.
