From Math Images
I'm a professor of mathematics at Swarthmore College. I've spent a lot of time thinking, writing and talking about writing mathematics, so I got involved with Math Images as another way to be involved with mathematical writing. In the Math Images project, I serve to help student workers frame doable topics (not too hard, not too long) and as one of the people who can serve as the senior advisor on the team for each page.
As for a general introduction about me, why repeat it here when I've done it best on my public webpage.
