I am an undergraduate at Zhejiang University, majoring in statistics. I have worked with Prof. Yang Yang and Prof. Xiaoye Miao on several projects about time series mining. Currently, I am working with YaleNLP group on for LLM evaluations and information retrieval.

I am broadly interested in natural language processing. My main interest lies in: (1) Model Evaluation: Detecting hallucination, benchmark long-context, instruction-following abilities. (2) Complex Reasoning: Exploring improved approaches for mathematical and domain-specific reasoning. I’m also interested in building AI applications and expanding my research into other modalities, such as vision and sequential data.
