Chengxiao Li

Hey! I am Chengxiao Li, a PhD student at AIoT Lab, CDS, HKU in Hong Kong, advised by Prof. Chenshu Wu. Before that, I received my B.Eng from Dalian University of Technology (DLUT) and my M.Sc from the University of Hong Kong (HKU).

My research interests lie in the following areas:

  • AI for healthcare, leveraging wireless perception sensors such as infrared array (IRA) and Wi-Fi to address healthcare–related perception tasks.

  • Wireless sensing, encompassing IRA, DToF Sensor, mmWave radar, and WiFi applications.

  • Human-centric AI, particularly in edge device–based healthcare and human–computer interaction.
