Hello there!

I'm Steve Trettel, a mathematician who is also interested in computers, physics, and language.

I'm currently an assistant professor at the University of San Francisco. This is both my personal and academic website, so you’ll find math I like explaining, updates on my computer graphics hobby, physics I'm learning, and some favorite meals, among other things.
