About Me

I am currently a final-year Ph.D. student at Department of Computer Science, City University of Hong Kong (CityU). My supervisor is Prof. Cong Wang. I received my B. E. degree in Information Engineering from South China University of Technology (SCUT) in 2013. I studied at Zhejiang University from September to December, 2013.

Research Interests

My primary research interests include cloud computing security, multimedia security, and privacy-preserving data processing.
