About me

I am enthusistic about media work, whether it's television, radio, or online.

I am a Senior Lecturer of Pure Mathematics at the University of Sheffield.  I grew up in Sussex, and have three degrees from the University of Cambridge.  After completing post-doctoral work at the Universities of Cambridge, Chicago and Nice, I took up my current post at the University of Sheffield.  I have published articles in eight different journals and given talks in 14 different countries.  I am known for my communication skills both in the research community and in teaching.  I was an early pioneer of YouTube lectures, beginning in 2007, and my videos have been viewed around 700,000 times to date.  I also work with secondary school pupils in my role running outreach for my department, and I help with maths at primary school as a volunteer.

My ambition is the rid the world of "maths phobia".  I like to bring personality, fun and hilarity to maths.  I love maths, I love people. I love performing, entertaining and educating at the same time.  I am good at explaining maths to people, and would love to do that for a wider audience. 

At the University of Sheffield I am known for my fun and wacky maths lectures.  I like baking, and like using food to explain maths whenever possible (see pictures below).  I can comment on and discuss any aspects of mathematics, statistics, universities, education and the mathematics curriculum, as well as gender and cultural issues.  I am also a concert pianist and give recitals regularly.

The "Perfect Cream Tea" story
12 TV and radio interviews in three continents!

In May 2013 I wrote a light-hearted maths paper about scones and cream, in response to an enquiry by a clotted cream company.  My aim was to find some genuinely rigorous maths in scones and cream, and to demonstrate mathematical methods in a fun context! You can read the paper here. I investigate different sizes of scones and the thickness of cream that would be necessary to get a good taste balance.  Given certain starting assumptions, I prove that clotted cream is better than whipped cream.

In the process, I had fun making scones of all sizes


and clotting my own cream, as I couldn't find any clotted cream in Sheffield.

The story took off! It was reported in the Daily Mail and on the front page of the Telegraph, as well as countless local papers and other papers as far afield as Australia and South Africa.
It was then mentioned in the BBC newspaper reviews on BBC Breakfast and Today, and online.

The University of Sheffield media team billed me as "The Math-ster Chef"!
We made this video about it.

...and then the interview requests started pouring in!
It began with Canada and Australia, and then moved closer to home.
Most of the interviews were on 28th May 2013.

1. CBC (Canada), interview on "As it happens"
2. ABC (Australia) live interview on Radio Canberra's breakfast show
3. Radio Devon (live)
4. Radio Ireland (live)
5. Radio Sheffield (live) - on Rony Robinson's programme
6. Look North (filmed at Radio Sheffield studios - clip below)
7. Radio Scotland (live)
8. Radio Gloucester (live)
9. Radio Cornwall
10. Radio Scotland (again! live)
11. ITV West (filmed by Yorkshire)
12. Radio Derby (live)

13. Interview by the Australian Institute of Mathematical Sciences for broadcast online

Here is the Look North clip:

After effects...

The next day, various shows were having an ongoing discussion about making maths fun, especially using food!  This included Radio 2 (Claudia Winkleman sitting in for Ken Bruce), and Channel Five (Wright Stuff).
This is exactly what I hope to achieve - people talking about maths as something fun and interesting, rather than as something dull and boring.  A common response was "I wish you'd been my maths teacher!" or "I don't remember maths being this fun!"

I'm also happy to see that various maths bloggers have written about this, such as aperiodical and flying colours maths, pointing out that it's not just another spurious "Perfect Formula for..." story, because it has rigorous mathematics behind it.

I'm also happy to see the work being used in outreach and educational contexts.

I was not paid by a clotted cream company for this work, in any way. Not even in cream...

Pictures of mathematical food I've created!

I am "The Math-ster Chef"!

1. Mathematical Battenburg cakes!
These exhibit the structure of the "Klein 4-group" and the "cyclic group of order 5".

2. Mathematical bagels!
The first is cut into two interlocking halves. The second is cut along a Möbius band...
