I’m working at Tencent AI Lab as a senior researcher. I received my Ph.D degree from the Chinese University of Hong Kong in 2021, under the supervision of Prof. Irwin King and Prof. Michael R. Lyu. Before that, I received my Bachelor degree and Mphil degree at Nanjing University in 2015 and 2017, respectively.

Currently, I focus on Large Language Models (LLMs), including various interesting topics.
