Ph.D. Student

I'm a 1st year Ph.D. student at the University of Hong Kong, with deep focus and passion on NLP and multimodal agents. I'm fortunate to get advised by Prof. Tao Yu and be a part of the XLANG Lab. Previously I got my bachelor's degree of Computer Science and Technology at Sun Yat-sen University.
