About me

I am a second-year Ph.D. student at the Department of Computer Science in the University of Hong Kong (HKU), supervised by Dr. Lingpeng Kong and Dr. Tao Yu in HKUNLP.
I received my Master degree in Fudan University, supervised by Prof. Qi Zhang in FudanNLP Group, and my Bachelor degree in Sun Yat-sen University.

Research

I am broadly interested in different topics in NLP. Currently, I focus more on interacting, understanding and improving large language models (LLMs):

• From general LLMs to task/domain specific efficient models by Data Distillation (ZeroGen, ProGen, SunGen, SymGen).

• Better interacting with LLMs via In-context Learning (SAIL, CEIL, OpenICL).

• Understanding and improving internal abilities (multilingual-reasoning).
