Brief Biography

Da-Zhi Sun received the Ph.D. degree under the supervision of Prof. Zhen-fu Cao in Computer Science and Technology from Shanghai Jiao Tong University, in 2006. From 2007-2011, Dr Sun performs the postdoctoral research under the supervision of Prof. Jin-Peng Huai in the Institute of Advanced Computing Technology at Beihang University. I am now an associate  professor in the School of Computer Science and Technology at Tianjin University. Dr Sun’s current research interests include information and network security, trusted computing, and applied cryptography.
