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.

Research

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:

  • Multi-Agent AI Systems: Interaction, coordination, and decision-making
  • Decentralized AI: Decentralized mechanisms and architectures
  • AI Marketplace Design: Markets, incentives, and mechanisms for AI
  • Game Theory & Mechanism Design: Strategic interactions in AI systems
