• I got the Ph.D. in cryptography from University of Wollongong, Australia in 2016. Before that, I received the B.Eng (2011) and M.Eng (2013) in computer science from National University of Defense Technology, China.
  
• My major research interests include public-key cryptographic designs, implementations and applications. Recently, I am mainly interested in post-quantum PKE/AKE and fully homomorphic encryption, as well as their applications for privacy-preserving computation and AI security.
  
• I was a visiting researcher at COSIC in KU Leuven, Belgium from 2019.03 to 2020.03. My host was Prof. Bart Preneel.
