Wanyang Dai received his Ph.D degree in applied mathematics jointly with industrial engineering and systems engineering from Georgia Institute of Technology, Atlanta, GA, U.S.A., in 1996, where he worked on stochastics and applied probability concerning network performance modeling and analysis, algorithm design and implementation via stochastic diffusion approximation. The breakthrough results and methodologies developed in his thesis were cited, used, and claimed as "contemporaneous and independent" achievements by some other subsequent breakthrough papers that were presented as "45 minute invited talk in probability and statistics" in International Congress of Mathematicians (ICM) 1998, which is the most privilege honor in the mathematical society. The finite element algorithm designed and implemented in the thesis to compute the stationary distributions of reflecting Brownian motions living in general-dimensional state space is also well-known to the related fields. 

He was a MTS (permanent) in End-to-End Network Architecture Department of AT&T Bell Labs and then (Alcatel-)Lucent Bell Labs/Network Systems, Atlanta, GA and Warren, NJ, U.S.A., from 1996-1999, where he was principal investigators and developers of several projects in telecommunication network architecture and design, network performance and financial engineering, operating system and database development, etc. with some project won "Technology Transfer". 

He is a full professor since 2004 in Nanjing University, where his research includes stochastic processes related optimization and optimal control, admission/scheduling/routing protocols and performance analysis/optimization for cloud computing and the next generation of wireless and wireline communication systems, forward/backward stochastic (ordinary/partial) differential equations and their applications to queueing systems, stochastic differential games, communication networks, financial engineering, etc. His achievements are published in "big name" journals including Operations Research and Queueing Systems. 

He is an Editor-in-Chief of International Journal of Information Engineering, editors or members of editorial boards of over 30 international journals ranging from pure mathematics to its applications, General Chairs, invited plenary/keynote speakers, and TPC members of over 20 IEEE and other international conferences, Vice Presidents and Standing Directors of several probability, statistics, and operations research societies. 

He was a visiting scholar in Academy of Mathematics and Systems Science of China, Beijing, China, in 2001, a Long Term Participant of IMA Annual Program of Probability and Statistics in Complex Systems: Financial Engineering, Communication Networks and Genomics in Institute of Mathematics and Its Applications (IMA), Minneapolis, U.S.A., in 2004, a visiting professor in Department of Systems Engineering and Engineering Management in Chinese University of Hong Kong, Hong Kong, China, in 2007.
