Wei Emma Zhang

About Me
I am a PhD student in School of Computer Science, The University of Adelaide. My supervisors are Prof. Michael Sheng, and Dr. Kerry Taylor . I got B.E. in Wuhan University and M.E. in Beihang University in China. Then I worked for Nuctech Company Limited as Software Engineer and Thomson Reuters as Senior Software Engineer before I came to Adelaide.
