I am the CTO of 屿智同行, where I lead Sprix AI, an A2A initiative for agent matching, orchestration, and transaction mechanisms. I am also an AI researcher and Senior LLM Algorithm Engineer at Alibaba International, and a Research Assistant at the Harvard Spatial Data Lab. I received my M.Eng. from Tsinghua University.

My work connects foundation-model research with real-world systems, with a focus on:

• Large language models, reinforcement learning, and alignment
• E-commerce search and multilingual query understanding
• LLM safety, reasoning, and misinformation robustness
• Spatiotemporal graph learning and intelligent transportation

As CTO at 屿智同行, I lead the Sprix AI project, focusing on A2A task matching, multi-agent scheduling and orchestration, and transaction algorithms for reliable agent-to-agent service exchange. Our open-source algorithmic research output, Sprix SAGE Router, makes state-aware SELF, COLLABORATE, and HANDOFF decisions for A2A agent networks.

At Alibaba International, I work on multilingual search and large-scale LLM systems across data engineering, distributed training, reinforcement-learning alignment, and production deployment. My research at Harvard explores spatial intelligence, mobility systems, and responsible AI.
