Email: yad.xie@gmail.com

I am currently a postdoctoral researcher in the Systems and Ubiquitous Networking (SUN) group in Tsinghua University, advised by Dr. Yuan He. I received my Ph.D. degree in the School of Computer Science, Beijing Institute of Technology in 2022, under supervision of Prof. Fan Li.

Research Interests

My research interests include Acoustic Sensing, Wireless Sensing, Privacy-Preserving Authentication, and Emerging Sensing Technologies.

  • Acoustic Sensing: WDevice-free activity recognition, physiological signal monitoring, and acoustic backscatter systems.
  • Wireless Sensing: Wi-Fi and mmWave based sensing for human activity and vital sign monitoring.
  • Privacy-Preserving Authentication: User authentication and continuous identity verification leveraging multimodal sensing.
  • Emerging Sensing Technologies: Metasurface-assisted sensing, event-camera-based tracking, and novel cross-modal approaches.
