My Ph.D. thesis is available here (submitted May 2007). It bears a striking resemblance to the paper "Detection of incompressible surfaces in hyperbolic punctured torus bundles".

I designed the cover art and all illustrations for the book Blast into Math! by my friend Julie Rowlett, published January 2013.

Talks

Slides and notes from some of my talks (see my CV for more):

On 23rd February 2008 I gave a talk to the University of Texas Mathematics Department's Saturday Morning Math Group (for an audience of around 200 high school students from nearby schools in the area), you can see a video of it here (scroll down to my talk).

Press

15 March 2013: Megan Gambino wrote a blog post for Smithsonian magazine on my 3D printed sculpture.

31 October 2012: Evelyn Lamb wrote a blog post for Scientific American on the "30-cell puzzle", a 3D printed puzzle by Saul Schleimer and me based on the 120-cell, one of the regular 4-dimensional polytopes.

23 August 2012: My sculpture "Dual Half 120- and 600-Cells" (joint work with Saul Schleimer) won the "Best Use of Mathematics" prize (one of four prizes awarded) at the Bridges conference 2012. It was featured in a slide show on the Scientific American website.

January 2012: I was interviewed for an article in the "Voice", a publication put out by the University of Melbourne, on "The language and art of maths". Here is the article. The online version of the article is missing the image (shown here) that went with the article. Alternatively, here is a pdf of the whole publication, which includes the article (on page 4) together with the photograph.

6 December 2011: I was interviewed by BBC Radio 5 about mathematical art and 3D printing. Here is the blogpost for the podcast. Here is the direct link to the mp3.

February 2008: I was interviewed on She Blinded Me With Science!, a show on the student radio station KVRX, talking about topology and juggling. You can listen to the interview here.
