Current Courses:

CSC 135: Computer Theory and Programming Languages
CSC 152: Cryptography

Since coming to Sacramento State I have taught CSC 1, 15, 20, 28, 130, 132, 135, 148, 151, 152, 206, and 252.

Research and Projects:

My research focuses on efficient and provably secure symmetric cryptography, especially universal hashing and its applications. If you are interested in working on a supervised project, I only take on students who have taken CSC 152 and have a project idea. If this is you, contact me.
