Biography

I am an Associate Professor in the Department of Mathematics and Computer Science at 69成人电影网 University. My research is primarily in cryptography, but I am also interested in algorithms and complexity. I am the coach for 69成人电影网's computer programming teams, and I am also currently the Computer Science Program Advisor.
