About Me
I am a postdoctoral researcher at Tsinghua University, working with Prof. Yiqun Liu. I received my PhD degree from Renmin University of China, supervised by Prof. Zhicheng Dou at the Gaoling School of Artificial Intelligence. My research mainly focuses on Information Retrieval and Natural Language Processing. Currently, I’m working on applying language models on IR problems including search results personalization, generative document retrieval, and retrieval-augmented generation.
