Biography

Jiaxin Jiang is now a senior research fellow working with Prof. Bingsheng He in School of Computing, National University of Singapore, and will join Zhejiang University in July 2026. Before that, he received his Ph.D. degree in Computer Science and Technology at Hong Kong Baptist University University, supervised by Prof. Byron Choi and Prof. Jianliang Xu in 2020 and B.E. degree in Computer Science from Taishan College, Shandong University in 2015 (Taishan College operates a 'pilot class' under the guidance of the MOE, selecting 15 students from an annual pool of 10,000 freshmen). He worked closely with Prof. Wenfei Fan and Dr. Jingbo Xu from 2015 to 2017.

His research is grounded in high-performance graph computing, targeting emerging graph data management problems in dynamic graphs, real-time risk control, and the LLM/Agent era. He designs practical algorithms and systems that can be deployed in real-world scenarios. He is looking for highly self-motivated undergraduate, master's, and Ph.D. students who are eager to explore new ideas, systems, and technologies.
