Chujie Zheng 郑楚杰

Welcome! I am a fourth-year Ph.D student of THU CoAI group, advised by Prof. Minlie Huang. Prior to my Ph.D study, I received my B.Sc degree from Dept. of Physics, Tsinghua University.

I have a broad research interest in building trustworthy language models, with current focus on improving their robustness and alignment. Previously, I conducted research on language models’ social good, especially in empathetic dialogue systems. I have also built a series of popular NLP datasets, including ChID, KDConv, ESConv, and CDConv.
