I am currently a visiting researcher working in the INK Lab at University of Southern California (USC), and will join the Viterbi School of Engineering – Computer Science Department at USC as a Postdoctoral Research Associate in Fall 2024, advised by Xiang Ren. I received my Ph.D. from Fudan University in October 2023, under the supervision of Zhongyu Wei. Before that, I received my Bachelor’s degree in Software Engineering from Fudan University. During my PhD, I’ve also spent time with the INK Lab at University of Southern California, advised by Xiang Ren.

My primary research interests include Natural Language Processing and Machine Reasoning, with a current focus on testing and improving LLMs Reasoning and Neuro-symbolic Integration.
