CV

Jiongchi Yu

Hello, I am Jiongchi Yu (俞炯弛). Many people also call me TTFish. I am a Ph.D. candidate in the School of Computing and Information Systems at Singapore Management University (SMU) supervised by Prof. Xiaofei Xie.

I received my bachelor’s degree from Zhejiang University, advised by Prof. Zhikang Xu and I was fortunate to take the guidance of Prof. Fan Zhang. I served as the team leader of Zhejiang University Supercomputing Team (ZJUSCT) for two years and helped reconstruct public services (e.g. ZJU Mirror).

I am open to all sorts of communication. Please feel free to reach out via emails or schedule an online meeting anytime 😃!

NEWS

My primary research focuses on the testing and security of cloud-native infrastructure. I am also working on (multi) agentic LLM systems for software engineering and security domain.
