I am a second-year Ph.D. student at the University of Southern California, advised by Prof. Robin Jia. Before that, I interned at GAIR Lab, woking with Prof. Pengfei Liu. I received my master’s degree from Fudan Univeristy, advised by Xipeng Qiu, and obtained my bachelor’s degree from the University of Chinese Academy of Sciences in 2021.

I am broadly interested in studying how current language models fail. My research focuses on analyzing and mitigating their limitations in problem-solving and human interaction. Ultimately, I aim to make language models more useful and reliable under limited resources.
