Yuqiang Sun (孙宇强 in Chinese) is now a research fellow at Nanyang Technological University. He got his Ph.D. degree in School of Computer Science and Engineering @ Nanyang Technological University, supervised by Prof. Yang Liu. Before Ph.D. study, he got his bachelor degree in Sichuan University. His research interests include program analysis, vulnerability detection and patch generation. He hopes to collaborate with more innovative researchers on various exciting topics in software engineering, program analysis, vulnerability detection, and self-evolving LLM agents in software engineering or software security.
