I am a third-year Ph.D. student at Rutgers University working with Prof. Dimitris N. Metaxas. Previously, I worked with Prof. Yongfeng Zhang (May 2024–June 2025). Before joining Rutgers, I was a Senior Machine Learning Engineer at Ant Group, with MLE internship experience at Tencent, ByteDance, and Ant Group. I worked as a Research Intern at Meta (May–Aug 2025; May–Dec 2026).

My research interests focus on Reinforcement Learning and LLM Agents, especially agentic memory, agent harness / scaffolding, and RL for LLM agents. If you are interested in my research or potential collaboration opportunities, please feel free to contact me by email.

I am currently looking for full-time positions and research internships — please reach out if there is a fit!
