I am now a third year Ph.D. student in THUIR, Department of Computer Science and Technology in Tsinghua University (THU), Beijing, China. Before joining THU, I received the B.Eng.(2019) M.Eng.(2022) in South China University of Technology (SCUT) and Institute of Software, Chinese Academy of Sciences (ISCAS) respectively. My supervisors are Prof. Shaoping Ma, Prof. Yiqun Liu and Prof. Qingyao Ai. My major research interests are about Large Language Models, Retrieval-Augmented Generation, preference alignment, text retrieval/reranking, knowledge enhanced models, etc.
I also served as a reviewer/PC-member for SIGIR, ACL, WWW, CIKM, and COLING.

I’m an enthusiast of a diverse array of craft beers, ranging from crisp wheat beers to robust IPAs and everything in between. I’m always on the lookout for exceptional brews from various corners of the globe. Whether it’s the refreshing notes of a Belgian Witbier, the hop-forward complexity of an IPA, or the subtle elegance of a Saison, I relish the opportunity to savor and discover the craftsmanship behind each unique flavor profile!🍻
