Courses Often Taught By Me:

CSC 15: Programming Concepts and Methodology I (Every semester)
CSC 140: Advanced Algorithm Design and Analysis (Spring of even-numbered years)

I have also taught CSC 1, 28, 130, 132, 148 and 206, but not recently.

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, please read this.
