If you're not a mathematician...

In a previous life I was a research mathematician. I thought a lot about gadgets called three-dimensional manifolds. They turn out to be really interesting and related to cool things like DNA and the shape of the universe.  Here's a (relatively) accessible account of what that's all about which I wrote sometime around 2012:

If you are a mathematician...

My research was mainly in 3-dimensional topology and geometry. All my papers are on the arXiv. The two I'm  most proud of are this one, joint with Joel Hass:

...and this one, joint with my old PhD advisor, Marc Lackenby:

Wait there's more!

Occasionally I still think about research mathematics, but not very often. If you're reading this and you're a graduate student in 3-manifold topology and want to hear some cool ideas for projects that I've not had time to pursue, feel free to email me.
