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 contact me 😃.


My current research focuses on testing and security issues of Cloud Native Infrastructure.
