I received my B.E. degree from Qingdao University, China in June 2018. In the same year, I was admitted to study for a M.Sc. degree in Nanjing University under the supervision of Prof. Qing Gu. Currently, I am working with Prof. Qing Gu and Assistant Professor Zhiwei Jiang for a Ph.D. degree.

Main Research Interests

I have a broad interest in large language model and natural language processing. My prior research experience included both emotion-cause pair extraction, open intent classification, multi-label text classification, essay scoring, and so on.
