Zhiyu Fan

Bio

I'm a Principal Researcher at Huawei Centre for Software Excellence. I earned my PhD degree from School of Computing at the National University of Singapore, where I was advised by Prof. Abhik Roychoudhury. Previously, I obtained my Bachelor's degree in Computer Science from SUSTech in China, where I was advised by Prof. Shin Hwei Tan.

My research interests focus on the intersections of automated program repair, automatic programming, including exploring the next-generation autonomous software development paradigm and enhance developers' trust in this process. During my PhD, I work on program repair for intelligent tutoring (TOSEM22, ISSTA23, CSEE&T25), program repair of AI programs (ICSE23), explorations on AI (i.e. LLM) programming (ISSTA24a, ISSTA24b)
