Jiawei Chen   陈家慰

I am a Ph.D. Candidate (from 2019.09) in the Chinese Information Processing Laboratory at the Institute of Software, Chinese Academy of Sciences, under the Supervision of Professor Xianpei Han.

My research interest is Information Extraction and Retrieval-Augmented Language Models.

I plan to graduate in 2025.
