I am currently a Research Fellow in the Department of Computer Science, National University of Singapore. I work on Database Systems, advised by Prof Beng Chin Ooi.

I obtained my PhD degree in Computer Science from Renmin University of China in 2023, under the supervision of Prof Xiaoyong Du and Prof Wei Lu. I was a visiting PhD student in National Univeristy of Singapore, supervised by Prof Beng Chin Ooi. I received my Bachelor’s degree from Zhongnan University of Economic and Law. I also worked in Tencent as a Research Intern from 2017 to 2023.

My current research interests: (1) AI-powered Database Systems; (2) Transaction Processing.
