About Me

    I am a professor in Computer Science at the San Diego State University.


    I received my B.S. in Electrical Engineering and M.S. in Computer Engineering both from Hefei University of Technology, Hefei, China. I received my Ph.D. in Computer Science from New Mexico Institute of Mining and Technology in May 2006.
