I am a 4th year Ph.D. student at School of Computing and Information , University of Pittsburgh at present. My advisor is Dr. James B.D. Joshi. I also work as a research assistant at the Laboratory for Education and Research on Security Assured Information Systems (LERSAIS).

I did my M.S. in Computer Science from Beihang University. Prior to that, I had my B.E. from Northwestern Polytechnical University. For more information, see my Curriculum Vitae.

Areas of Specialization

My research work covers a range of areas : applied cryptography, cryptography based access control, secure computing, security and privacy issues in cloud/edge computing. Currently, I am working on various issues such as secure multi-party computing and public ledger to build trustworthy, collaborative and transparent third-party authority infrastructure for advanced crypto systems. I am also exploring approaches to achieve privacy-preserving collaborative machine learning models by secure multi-party computing, approximate computing, etc., and efficient and generic approaches to achieve machine learning models over encrypted data.
