Yik-Chung Wu

Yik-Chung Wu received the B.Eng. (EEE) degree in 1998 and the M.Phil. degree in 2001 from the University of Hong Kong (HKU). He received the Croucher Foundation scholarship in 2002 to study Ph.D. degree at Texas A&M University, College Station, and graduated in 2005. From August 2005 to August 2006, he was with the Thomson Corporate Research, Princeton, NJ, as a Member of Technical Staff. Since September 2006, he has been with HKU, currently as an Associate Professor. He was a visiting scholar at Princeton University, in summers of 2015 and 2017.

His research interests are in general areas of machine learning, signal processing and communication systems, and in particular distributed algorithms, and large-scale optimization theories. Dr. Wu served as an Editor for IEEE Communications Letters, and IEEE Transactions on Communications, and is currently an Associate Editor for IEEE Transactions on Signal Processing, and an Editor for Journal of Communications and Networks. He was a TPC member for over 50 IEEE major conferences. He received four best paper awards in international conferences, with the most recent one from IEEE International Conference on Communications (ICC) 2020. He is a senior member of the IEEE.
