About Me

I am a postdoctoral fellow at City University of Hong Kong (CityU) and Hong Kong University of Science and Technology (HKUST), supervised by Prof. Clint Ho. I obtained a Ph.D. in Artificial Intelligence from Huazhong University of Science and Technology (HUST) and a Ph.D. in Data Science from CityU in 2024. Previously, I received my B.Sc. in Vehicle Engineering and M.Sc. in Mechanical Engineering from Beijing Institute of Technology (BIT) in 2017 and 2020, respectively. 

My research lies in the intersection of robotics, control, optimization, and learning. My research goal is to build secure, intelligent, and autonomous robot systems assisting humans in hazardous and labor-intensive tasks. I have undertaken various projects related to autonomous driving, unmanned aerial vehicles, legged locomotion, and swarm robotics.
