I am currently an algorithm engineer in Meituan, focusing on recommender system for online advertising platform, especially user interest modeling, auction design, bidding strategies, and social recommendation. Prior to that, I received my Ph.D. degree from the CS department, Shanghai Jiao Tong University (SJTU) in June 2023, advised by Prof. Xiaofeng Gao. I was a visiting research scholar in the N-CRiPT, National University of Singapore (NUS) from January 2022 to January 2023, advised by Prof. Anthony K. H. Tung. I was a research intern at Tencent TEG in 2021. I received B.E. in Computer Science from Ocean University of China (OUC) in June 2018, where I was advised by Prof. Yingjian Liu.
