About Me

Xie ZHANG is currently a Ph.D. student in the CS department , at the University of Hong Kong (HKU). He is a member of HKU AIOT Lab which Prof. Chenshu Wu directs. Previously, he received his master's degree in the major of Pattern Recognition and Intelligence Systems from the School of Intelligent Systems Engineering, Sun Yat-sen University. During his master's degree, he focused on Wi-Fi sensing, under the supervision of Prof. Wanquan Liu. Before that, he received his B.A. degree in the major of Software Engineering, at Sun Yat-sen University.

Research Interests

  • My research focuses on wireless sensing in the ubiquitous computing field. Specifically, I am dedicated to constructing novel sensing systems for smart home applications, elder monitoring, and human-computer interaction. Currently, I am working on data-driven sensing technologies as follows:
    - WiFi sensing
    - Cross-modal sensing
    - Human Activity recognition

There is but one truly serious philosophical problem, and that is suicide. Judging whether life is or is not worth living amounts to answering the fundamental question of philosophy.
