Biography

I am currently pursuing the Ph.D. degree at the University of Science and Technology of China (USTC), supervised by  Houqiang Li and  Wengang Zhou. I received the B.E. degree from Shandong University (SDU) in 2021, where I was advised by Liqiang Nie and Xuemeng Song.

My research interests include retrieval-augmented language models and reinforcement learning. I am presently working on alleviating hallucinations in retrieval-augmented language models.
