About Me

I am currently a Postdoctoral Fellow at Department of Computing, The Hong Kong Polytechnic University (PolyU). I received my Ph.D. from the same department, advised by my insightful supervisor Prof. Yuanqing Zheng. I received B.E. degree in Communication Engineering from School of Information and Communication Engineering, University of Electronic Science and Technology of China (UESTC). My research interests include AIoT and Wireless Networking.
