I am a fourth-year Ph.D. student at Wangxuan Institute of Computer Technology, Peking University, advised by Prof. Yansong Feng and Prof. Dongyan Zhao. I am glad to visit University of California, Los Angeles and collaborate with Prof. Kai-Wei Chang and Prof. Nanyun Peng in 2023. I received my BSc degree from School of Electronic Engineering and Computer Science, Peking University and BEc degree from National School of Development in 2020. My research interests are in natural language reasoning and causal inference.
