About Me

I’m a fourth-year Ph.D. candidate at University of Southern California working with Prof. Muhao Chen. I’m also fortunate to have worked with Prof. Xiang Ren and Prof. Yangqiu Song. My research interest lies in natural language processing and machine learning. In particular, I’m interested in developing information extraction models with minimal supervision. Before joining USC as a Ph.D. student, I graduated with a Bachelor’s degree from HKUST in 2018.
