Renjie Sun

Currently, I’m a lecturer at the School of Computer Science and Technology, Zhejiang Gongshang University (ZJSU). I obtained the Ph.D. degree in Software Engineering from East China Normal University in 2025, under the supervision of Xuemin Lin and Xiaoyang Wang. Previously, I received my Bachelor’s degree in Computer Science and Technology from Henan University in 2017, and my Master’s degree in Computer Technology from Zhejiang Gongshang University in 2021.

My research interests lie in graph data mining, signed data analysis, and social simulation.
