I am currently an Assistant Professor in the Department of Computing at The Hong Kong Polytechnic University (PolyU). I received my Ph.D. degree in Computer Engineering from Stony Brook University, where I had the privilege of working with Prof. Yuanyuan Yang. Prior to that, I earned a Bachelor's degree in Telecommunications Engineering from Xidian University in Xi'an, China.

Research interests

My research broadly focuses on networking and algorithm design for distributed computing, with a particular emphasis on quantum computing and edge environments.

  • Distributed quantum computing
  • Edge computing and networks
  • Edge AI
  • LEO satellite networks
