About
I am a Ph.D. student at the School of Computer Science, The University of Auckland, and a member of the Civilised Agent Lab.
Previously, I completed my Master's degree in Computer Technology at the University of Electronic Science and Technology of China (UESTC) in 2025. I also earned my Bachelor's degree from UESTC in 2022.
My research primarily focuses on two areas: analyzing and optimizing interactions in multi-agent AI systems, and designing effective mechanisms for the AI marketplace. I am also interested in mobile computing, wireless communications, and networking.
For a full academic record, please see my CV.
