About Me

I did my Ph.D. study in Georgia Institute of Technology, under the advisement of Prof Ling Liu. Previously, I obtained my B.Sc. and M.Sc. in Computer Science, resp. in 2006 and 2009, both from Fudan University, Shanghai, China.

My research interests are broadly on distributed systems and security. My current focus is on the following two topics:

  1. Building secure and high-performance big-data systems in the cloud
  2. Secure multi-source data analytics with applications in eHealthcare, social networks and corporate IT
    • Privacy-preserving index of Healthcare information networks (security) [Project details]
I value system building and implementatable research. Details of my research can be found in my research projects.
