About Me

I am a final-year Master’s student at the School of Computer Science and Technology, Beijing Jiaotong University (BJTU), supervised by Prof. Shengnan Guo and co-advised by Prof. Huaiyu Wan. I received my Bachelor’s degree in Computer Science and Technology from Beijing Jiaotong University. My main research interests include reinforcement learning, data mining, diffusion models and large language models.

Research Roadmap

I have been working on decision-making policies for real world in two areas: traffic signal control (TSC) and sim-to-real reinforcement learning (RL). My research roadmap is shown above.

Data-missing traffic signal control with diffusion models (TSC)
Cross-city traffic signal control by Shapley value enhanced multi-task RL (TSC)
Cross-domain policy adaptation for sim-to-real tasks with diffusion models (RL)

Towards more generalizable and robust policies, I am working with collaborators on scenario generation for traffic simulation and exploring the utilization of foundation models (e.g., LLMs, VLMs and VLAs) in decision-making tasks.
