"Where am I?"
You've somehow stumbled onto my new and improved website at the Mathematics Department here at the Massachusetts Institute of Technology. I'm quite tall. I do math. There's more, but that's the gist of it.
"OK, so what's here?"
At the top there you'll find a menu that you can use to navigate to pages about my research, courses I've taught, the seminars I'm involved in, links to some organizations I support, and, of course, how to get in touch with me.
