Welcome to my homepage!

Hi! I am a final-year undergraduate at Yuanpei College, Peking University, majoring in Data Science with a minor in Philosophy.

My research is driven by a philosophical curiosity rooted in epistemology, about how large models integrate perception and language to gain knowledge. I focus on Multimodal AI and AI Reasoning, with a interest in building more intelligent, efficient and interpretable AI systems. My long-term goal is to develop AI that not only advance technical capabilities but also enhance access to quality knowledge and promote equity for underserved communities.
