I work at Eonite Perception, doing software engineering and thinking about math problems. I've also worked/studied at Google, Caltech, UC Berkeley, and Brandeis.
My mathematical interests are largely in algebraic geometry, particularly foundational questions about algebraic stacks. See my Research page for more information. Lately, I've been thinking more about probability, information, and inferrence.
I've taught several courses over the years. Check out the course pages.
is a question and answer site for professional mathematicians. I founded it and helped to make it successful. You can read about it in the Notices, from the Simons Foundation, in the Atlantic, and on many different blogs.
As a real-time TeXer, I've accumulated some course notes that I find to be useful references.
Okay, I don't really blog, but I do sometimes write up something interesting that I think about. Here are some links to those things:
