This semester I'm holding regularly scheduled office hours MTR from 9:30-10:30 AM. You may also contact me for an appointment to see me (or just drop by, I'm probably in).
I've long maintained, contrary to many people's expectations, that mathematics is not something that only smart people do, but that math is something that people can do to get smarter. Apparently, there is some research that backs this idea up! Check out this great article in The Atlantic for more information.
As time permits in coming weeks and months I will post information here about my research program. Most of my current work is in the area of abstract polytopes. A list of my published works.
Learn more about what I and my family are up to. You can also follow me on twitter or Tumblr, though unless you are related to me, I can't imagine why you would do any of those things.
I'm very interested in the intersection between mathematics and art. I maintain a site debunking mathematics myths. I'm also interested in projects dedicated to using mathematics to advance social justice. I'm not involved, but this one sure looks cool!
I apologize that the look of the linked sites I maintain is so incoherent, someday when I have time I'll come up with a master plan and implement it everywhere, but in the meantime, hodge-podge is the order of the day. This site is definitely a work in progress, and always will be.
