Guangba Yu
Postdoctoral Researcher, CUHK
I am a postdoctoral researcher in ARISE Lab at The Chinese University of Hong Kong, mentored by Prof. Michael R. Lyu.
I obtained my Ph.d and M.Eng degrees from Sun Yat-sen University, supervised by Prof.Pengfei Chen.
I was a Ph.D. software engineering student researcher at WeChat in 2022-2023, mentored by Yuetang Deng.
😃 I always welcome the opportunity to collaborate research topics about system reliability. Feel free to drop me an email if you're interested in connecting with me.
