Biography

Wing is an Associate Professor in the Department of Information Engineering and the Director of the Mobile Technologies Center at the Chinese University of Hong Kong (CUHK). Before joining CUHK, he spent 10 years in the US with Bell Labs, Holmdel and Qualcomm, San Diego. Wing received his BSEE degree from the University of Hong Kong and MS and PhD degrees in Electrical and Computer Engineering from the University of Texas at Austin. His research interests include System Modeling, Networking Protocol Design and Performance Analysis, Network/Systems Security and Mobile Computing. His recent research projects include: Online Social Network Privacy and Vulnerabilities, Authenticated 2D barcodes, Decentralized Social Networking protocols/systems and Resource allocation for Large-scale Computing Clusters. He serves on the Technical Program Committee for various international conferences including ACM Sigmetrics, IEEE Infocom, SECON, ICC, Globecom, WCNC, VTC, and ITC. He also served as the Guest Editor for the Special Issue on High-Speed Network Security of the IEEE Journal of Selected Areas in Communications (JSAC). Wing holds 17 US patents with a few more pending. His research findings have been published in more than 80 scientific papers in major international journals and conferences. Wing is a Senior Member of IEEE and a member of ACM and Tau Beta Pi.
