I am a fourth-year PhD student in the School of Computer Science at Peking University, advised by Prof. Zongqing Lu. I received my Bachelorโs degree in 2021 from the School of Information Science and Technology at PKU.
My research interests lie in Multimodal Large Language Models (MLLMs), Embodied Artificial Intelligence, and Reinforcement Learning. In particular, I focus on vision-language understanding and generation, vision-language-action (VLA) modeling, and LLM-based autonomous agents.
