I am a CS Ph.D. student at UNC Chapel Hill, supervised by Prof. Mingyu Ding and Prof. Huaxiu Yao. I received both my Bachelor’s and Master’s degrees from Tongji University. I interned at UC Berkeley as a visiting student researcher, where I collaborated with Prof. Masayoshi Tomizuka, Prof. Mingyu Ding, and Dr. Wei Zhan.
My research interests include LLM/VLM, RL , and embodied AI. And my research goal is to improve the performance of LLMs and VLMs through reinforcement learning and other post-training techniques, and to leverage these models to build efficient and intelligent agents capable of interacting with the physical world (embodied intelligence) and driving scientific exploration (AI for Science).
I am actively seeking 2026 summer internships. Let’s connect!
