About me

I am a researcher in the Data Science and System Security (DSSS) department at NEC Labs America in Princeton, NJ. My research focuses on building scalable and resilient systems for the next generation of AI.

Previously, I was a Postdoc Associate in the Department of Computer Science at Yale University, working with Prof. Robert Soule and Prof. Avi Silberschatz.

I received my Ph.D. from the University of Virginia, advised by Prof. Helen Shen. I obtained my M.S. from Columbia University and B.S. from USTC.

Research Interests

• LLM Agents & Multi-Agent Systems: Designing collaborative AI architectures.

• Distributed Systems: Optimizing large-scale data processing and model serving.

• Reinforcement Learning: Applied to system optimization and decision making.

• Datacenter Networks: Enhancing cloud infrastructure performance.
