I am an incoming postdoctoral research fellow at the School of Computing, National University of Singapore. I obtained my PhD from the University of Science and Technology of China in March 2023, supervised by Prof. Xiangnan He. Prior to that, I received my B.Eng. degree from USTC in 2019. My recent research focuses on recommendation systems and LLM/Agent personalization. I have authored over ten publications featured in renowned conferences and journals such as SIGIR, CIKM, and TOIS. Notably, my research on causal debiasing earned the distinction of Best Paper Honorable Mention at SIGIR 2021. Additionally, I have served as a Program Committee (PC) member and reviewer for esteemed conferences and journals, including TOIS, TKDE, TIST, TKDD, TNNLS, WSDM, SIGIR, RecSys, SIGKDD, and AAAI.
