I am a fourth-year Ph.D. student in Computer Science at Zhejiang University’s DCD Lab, jointly advised by Prof. Yang Yang and Prof. Jiarong Xu. I also collaborate closely with Prof. Carl Yang at Emory University. I graduated from Chu Kochen Honors College with bachelor’s degree in Computer Science and I have also been a visiting student at Fudan University and the National University of Singapore.
My research mainly focuses on structured data and large language models, including LLM agents, reasoning, alignment, and embodied intelligence. I am particularly interested in multi-agent systems, agentic reinforcement learning, agent benchmarks, environment-grounded agents, and embodied agents such as humanoid VLA. Furthermore, I have a strong background in graph machine learning, including transfer learning, robustness, and privacy.

🍉 Publications
My earlier work focused on graph learning foundations and foundation models for structured data, especially transfer, robustness, and privacy. My current research mainly centers on large language models, including LLM agents, multi-agent interaction, agentic RL, reasoning, grounding and evaluation, preference modeling for alignment, and embodied agents such as humanoid VLA.
🤖 Agentic RL, Multi-Agent Systems, and Agent Benchmarks
This line of work studies agents as complete systems: how they interact in social environments, how they improve through agentic RL, and how they are grounded and evaluated in realistic long-horizon tasks.

Beyond acting well, agents also need to align with nuanced and diverse preferences. This work studies how preference structures can be organized explicitly instead of treated as a flat signal.
