Multi-Agent AI Systems
Analyzing and optimizing interactions in multi-agent AI systems.
I am a Ph.D. student at the School of Computer Science, The University of Auckland.
Previously, I received my M.S. degree in Computer Technology from the University of Electronic Science and Technology of China (UESTC) in 2025 and my B.S. degree from UESTC in 2022.

My research lies at the intersection of Artificial Intelligence and Economic Theory, with a focus on understanding and optimizing interactions among intelligent agents and designing effective mechanisms for emerging AI ecosystems.
Specifically, my research topics center on Multi-Agent AI Systems and AI Marketplace Design, especially in:

Analyzing and optimizing interactions in multi-agent AI systems.

Designing effective mechanisms for the AI marketplace.
