🙋 About Me

📚 Biography: Gou Tan (谭苟 in Chinese) is in the third year of his Ph.D. at Sun Yat-Sen University (SYSU), supervised by Prof. Pengfei Chen and Prof. Chuanfu Zhang. He is also a visiting student at Singapore Management University (SMU), supported by a CSC (China Scholarship Council) fellowship and advised by Prof. David Lo and Prof. SHAR Lwin Khin. He received a B.E. degree from Sun Yat-Sen University in 2022.

🎓 I’m looking for remote internships anytime and full time roles starting in July 2027.

🔬 Research Overview

My research focuses on SE4AI (LLM/Agent Reliability, LLMOps) and AI4SE (AIOps, Code Vulnerability). I make LLM and agent systems more reliable and easier to operate. I also use AI to monitor software systems, diagnose failures, and improve code security.
