I'm an incoming PhD student at UC San Diego and am fortunate to be advised by Prof. Julian McAuley.

Currently, I'm a final year graduate student at Renmin University of China, advised by Prof. Wayne Xin Zhao, who runs the AI Box Lab. I had a wonderful half year visit at UCSD in 2022. My major research interest lies in the intersection of NLP and Information Retrieval.
