Mi Zhang

I am an associate professor at Institute of Computing Technology, Chinese Academy of Sciences. Previously, I was a Postdoctoral Researcher at The Chinese University of Hong Kong (CUHK), where I was a member of the Applied Distributed Systems Lab (ADSLab). I received my Ph.D. degree in Computer Science and Engineering from CUHK, under the supervision of Prof. Patrick P. C. Lee. My research interests include distributed systems, storage systems, and system reliability.
