University of Oxford,
24-29 St Giles',
Only a few minutes walk from Edinburgh into the Pentland hills...
(Follow the link and zoom in for a change of perspective.)
I am interested in many things geometric; in particular, analysis on metric spaces, geometric group theory, hyperbolic groups ...

- You can draw your own self-affine (Bedford-McMullen) carpets
- Your browser will ask you to accept a not very impressive security certificate. If you decline
it should still run, but you won't be able to save pictures. Also, the applet uses Java 1.6.

Expository notes (not for publication)
At the University of Oxford, I am primarily working with
and other members in the topology group.
Before coming here, I was a J.L.Doob research assistant professor at the
University of Illinois from 2008 until the end of 2010.
I was a graduate student at the University
of Michigan (2003-2008), where I worked with Bruce Kleiner. I also spent most of 2006-8 visiting the mathematics department at Yale.
Before that, I was an undergraduate at the University of
