About Me

I am currently a 3rd year Ph. D. candidate at Department of Computing, The Hong Kong Polytechnic University (PolyU), 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 Low Power Wide Area Network (LPWAN), LoRa, Mobile Sensing.

Please find more about me in my CV.
