• In 2011, 2012, 2013, & 2014 I have given workshops on “Knot Maths” to school-children aged 13-14 as part of the Royal Institution Mathematics Masterclasses in Leeds. Handout here [pdf].

• Maths Excursion talk at Leeds Univeristy on the topic of Pick’s Theorem and Ehrhart Polynomials (February 2012). Slides here [pdf].

• Logic Seminar at the University of Leeds, on the topic of *Concrete Incompleteness.* (October 2010) Slides and blogpost here.

• With Matt Daws, I have developed a 2 hour workshop on Knot Theory for sixth-formers, which we have given several times to date, including as part of Leeds Festival of Science. Handouts and blogpost here.

• Also with Matt Daws, I have developed a 2 hour workshop on Pick’s Theorem for sixth-formers, which we have given once to date (March 2013) as part of Leeds Festival of Science.

• I have given talks and masterclasses on various aspects of mathematics (including prime numbers, tessellations, infinity, knot theory, waves) at schools around Yorkshire.

• In February 2007, I appeared on Channel 4′s radio show *The Tube*, discussing Goldbach’s Conjecture with Alex James (of *Blur* fame) in front of an audience of screaming teenage rock fans. (Write-up here.)

• October 2007, I gave a talk about *e* and transcendental numbers at CafĂ© Scientifique in Chapel Allerton, Leeds, in front of a less screaming, less teenage audience. See photos here.
