Mi Zhang

I am an assistant researcher at Institute of Computing Technology, Chinese Academy of Sciences. Before that, I was a postdoctoral researcher at The Chinese University of Hong Kong and a member of the Applied Distributed Systems Lab (ADSLab). I received my Ph.D. degree in the Department of Computer Science and Engineering at The Chinese University of Hong Kong, under the supervision of Prof. Patrick P. C. Lee. My research interests include distributed storage systems, erasure coding and reliability analysis.
