Secret Santa in R

Our office just exchanged presents for Secret Santa, a tradition where each person is randomly assigned someone else to give an anonyous gift. One of the challenges of Secret Santa is keeping the pairs of gift-givers and receivers both random and secret. How can you do this while also taking part yourself? Using R, of course!

Poster: PageRank and the Bradley–Terry model

Here is my poster that I presented at the 2nd IMA Conference on the Mathematical Challenges of Big Data in London on 1st–2nd December 2016. It is entitled “PageRank and the Bradley–Terry model: Measuring influence with the Scroogefactor”.

Sent to Coventry

I have just moved to the University of Warwick to start my PhD in Statistics. So far most of the people I have met would regard Coventry as a bit of a downgrade from Edinburgh, but the Warwick campus seems to make up for it.

Edinburgh Broadband Map

Despite living in the capital city of Scotland, my home broadband speeds (especially upload speeds) are painfully slow. There is no fibre-optic offered on my road, while my friend two streets over enjoys super-fast internet. It turns out, through the power of data visualisation, that EH16 is a bit of a broadband speed “notspot” along with a few other slow neighbourhoods throughout Edinburgh. The big empty hole to the east of the city centre is Arthur’s Seat and Holyrood Park.

Everything is awesome

Today I took part in the Lego Calculator Challenge, an event that was run as part of Edinburgh University’s Innovative Learning Week. The day included revising the finer points of adding in base 6 and learning about how people managed to do complicated calculations on mechanical computers before Alan Turing invented the Casio fx-83.

Twitter score predictions are not infallible

This evening saw the Netherlands face Spain for their first match in the group stage of the 2014 Fifa World Cup. 604 score predictions were made on Twitter in the hour before kick-off. When the final whistle blew, 100% of them had missed the mark.

Data mining: tea is for Twitter

As part of my first foray into data science, I decided to have a go at opinion mining on Twitter. It’s common knowledge that everything stops for tea, but how much does the Twittersphere agree? And what else are microbloggers saying about the drink?

T-set mug

The set of all t makes the perfect tea set for mathematicians and other numerate geeks. A natural accompaniment to your Student’s t-distribution teapot, the t-set lets you collect mugs in a mathematical way.

Contours Magazine

Contours magazine is a student publication produced by the University of Edinburgh School of Mathematics, featuring interviews with maths lecturers. I was editor and graphic designer for the 2013–14 edition. Click here to read it on Issuu, or pick up a hard copy from the King’s Buildings campus.
