I am an algorithm engineer at Alibaba Group, focusing on RecSys and LLMs. Before that, I received my Ph.D. from Institute of Information Engineering, Chinese Academy of Sciences, supervised by Prof. Tingwen Liu.

During 2025-2026, I received special offers from Alibaba (AliStar), ByteDance (筋斗云), Tencent (青云), Meituan (北斗), etc. I have also published several papers at top-tier conferences, including KDD, ICDE, WWW, SIGIR, ICML, ACL, CVPR and so on. If you are seeking any form of academic cooperation or have any questions, please feel free to get in touch.
