Hello! I am currently a Postdoctoral Research Fellow at the School of Computing and Information Systems (SCIS), Singapore Management University (SMU), working with Prof. Guansong Pang. Prior to joining SMU, I received my PhD degree from Nanjing University of Science and Technology (NJUST), under the supervision of Prof. Hui Yan. My research interests focus on graph data mining, graph anomaly detection, and graph foundation model.
