Yunqiao Yang (杨昀樵)

I am a 1st year Ph.D. student at the Multimedia Laboratory (MMLab), The Chinese University of Hong Kong (CUHK), advised by Prof. Hongsheng Li.

I received my B.E. in Electronic Science and Technology from Shanghai Jiao Tong University (SJTU) in 2025.

My research interests lie in Large Language Models (LLMs), specifically focusing on Preference Optimization, Mathematical Reasoning, and Code Generation Agents.
