Currently, I am a professor with the College of Computer Science and Technology, Nanjing University of Aeronautics and Astronautics, China. From August 2012 to July 2014, as a JSPS postdoctoral fellow, I worked at Prof. Tsuyoshi Takagi's group, Institute of Mathematics for Industry in Kyushu University, Fukuoka, Japan. The fellowship is supported by JSPS (Japan Society of the Promotion of Science) project of Japan. Before that, I received my B.A. in science communication in 2007 and PhD degree in computer science in 2012, respectively, both from University of Science and Technology of China (USTC).

I am interested in the area of applied cryptography and network security, secure outsourcing and privacy preservation in cloud computing and distributed computation etc.
