I am a Professor with Wangxuan Institute of Computer Technology (WICT, formerly known as Institute of Computer Science and Technology),
Peking University (PKU), China. I received B.S. in Information Sciences from Department of Information Management of PKU in 2000, M.S. and Ph.D. in Computer Science from Department of Computer Science and Technology of PKU in 2003 and 2006 respectively.
Research
My research interests include Natural Language Processing and Deep Learning. Previously, I was broadly interested in several research topics including document summarization, text generation, sentiment analysis, semantic parsing, multilingual and multimodal NLP. Recently, I am interested in exploring NLG evaluation, faithfulness and safety of LLMs, and cross-modal generation.
