Hi, I’m Jiake Ge (Jack). I am an Assistant Researcher at the School of Artificial Intelligence, Tianjin University. I received my Ph.D. from Renmin University of China in 2024, advised by Prof. Yunpeng Chai.
I currently serve as an Executive Member of the CCF Technical Committee on Databases and the CCF Technical Committee on Information Systems. My research focuses on intelligent database technologies (AI4DB–DB4AI) and intelligent data management. I have published more than ten papers in leading venues such as SIGMOD, ICDE, and The Web Conference (WWW), and I serve as a reviewer for VLDB, IEEE TKDE, WWW, KBS, and other top journals and conferences.
I have led national- and provincial-level research projects as well as teaching-reform projects. I was selected for the 2025 CCF Technical Committee on Information Systems Doctoral Dissertation Incentive Program, the National Funded Postdoctoral Researcher Program, the China Postdoctoral Science Foundation–Tianjin Joint Special Grant, and the Tianjin Postdoctoral Innovation Position Grant. I received the Best Paper Award at the 3rd International Workshop on Large-Scale Graph Data Analytics (LSGDA 2024) and was supported by the Outstanding Innovative Talents Program of Renmin University of China.
Recruiting Master's students for 2027, welcome students interested in my research directions to contact me!
