Teaching:

In Winter 2013, I am teaching Math / Stats 425: Probability

Writing Math:

If you are planning to write up any mathematics, either for one of my courses or for your own reasons, I strongly recommend using LaTeX. Even if you're not writing math, it's one of the best formatting languages available, and I highly recommend it. I've put together a few brief references to help you get started with LaTeX.

If you're already using LaTeX, I highly recommend using some sort of version control system. I use Mercurial. A very nice manual is available here. Even if you're not writing collaboratively, it subversion is a great way to manage all the different versions of papers that inevitably get generated. If you're an academic, you Bitbucket.org provides free mercurial hosting for all your projects.

Research:

My research focuses primarily on coding theory and cryptography. Below is a selection of my research papers

Online Cryptographic Resources:

If you're interested in learning about modern cryptography, there are a number of great references available online.
Most are aimed at graduate students in math or computer science with no previous background in cryptography.
