>Ph.D. @ Tsinghua_
Ph.D. student @ Tsinghua University (THUIR). I build capable, autonomous code agents — from the data that trains them to the rewards that guide them.
// 01 about
I am a fourth-year Ph.D. student at THUIR, Department of Computer Science and Technology, Tsinghua University, advised by Prof. Yiqun Liu. My research centers on building capable, autonomous code agents — spanning the full stack from training data and long-horizon reinforcement learning to reward modeling. I'm always happy to connect and collaborate with fellow researchers and engineers.

Code Agents
Building autonomous agents that understand, navigate, and modify large real-world codebases end to end.
Long-Horizon RL
Reinforcement learning that strengthens agents' long-horizon abilities — multi-step planning, sustained reasoning, and reliable task execution.
Information Retrieval
Dense retrieval, ranking, and retrieval-augmented generation — connecting models to the right knowledge at scale.
Reward Modeling
Designing reliable reward models and verifiers to guide, evaluate, and continually improve agent behavior.
