What doesn’t kill you makes you stronger.


I am Runxin Xu (许润昕), a master student at the Institute of Computational Linguistics in the School of EECS, Peking University, advised by Dr. Baobao Chang and Dr. Zhifang Sui. Prior to this, I earned my Bachelor’s degree at Shanghai Jiao Tong University advised by Dr. Xiaofeng Gao.

My research interests mainly lie in natural language processing, especially 1) document-level and few-shot information extraction, and 2) effective and efficient pre-trained language model.

I am actively seeking for engineer or researcher position (graduate in 2023). Please drop me an email (A@B,A=runxinxu,B=gmail.com) if you want to chat.
