Welcome to join us!

Our group is led by Prof. Guangyan Zhang.
We are one of the teams in China to start working on storage systems. Our group has produced around a hundred publications on international conferences like FAST, USENIX ATC, EuroSys, etc. as well as authoritative journals including IEEE TC, IEEE TPDS, ACM TOS, etc.
