From October 2016 I have been Chair of the Winton Centre for Risk and Evidence Communication. This Centre, generously funded by the David and Claudia Harding Foundation , is based in the Department of Pure Mathematics and Mathematical Statistics in Cambridge, and is dedicated to improving the way that quantitative evidence is used in society.

From October 2007 until December 2018 I was the Winton Professor for the Public Understanding of Risk in the Statistical Laboratory, Centre for Mathematical Sciences, University of Cambridge. I worked with a small team comprising Mike Pearson (web and animation), and Owen Smith (web), and our website was Understanding Uncertainty. This is an educational resource featuring the use of probability and statistics in everyday life, and makes extensive use of animations to help 'tell the story' of the data. Googling 'Uncertainty' should find it.

The Art of Statistics

sex by numbers cover
The Art of Statistics is a Pelican book published by Penguin. This is its Amazon site, which is good for reviews (although you might want to buy from a different source so as to encourage diversity in book sales).

It's had some good reviews from Nature, Evening Standard, Spectator, E and T magazine, Standpoint, Popular Science and particularly in the Financial Times.

I have done interviews for the Guardian podcast, RTE Business, Monocole radio.


The Cambridge Coincidence Collection started as part of filming for the BBC4 programme Tails you win: the science of chance , and since then over 5000 coincidences have been contributed to our website.

Teaching Probability

teaching probability cover Teaching Probability by Jenny Gage and myself is published by Cambridge University Press and forms the first book in a series from Cambridge Mathematics. This is the home page for the book, and this is the resource site for teachers.

Sex by Numbers

sex by numbers cover Sex by Numbers is published by Profile Books and the Wellcome Collection, and accompanies the Wellcome's excellent Institute of Sexology exhibition which runs until September 20th 2015. There is a rather neat animation that features some of the stats. Full details here.

The Norm Chronicles

The Norm Chronicles (with Michael Blastland) was published by Profile Books in June 2013. It has a promotional website.

Reviews (favourable!) have appeared in The Economist , Daily Mail , The Guardian , Sunday Times (Dominic Lawson) [paywall] , Bookbag , The Times , and a digested read in the Guardian .

Articles and interviews have appeared in Daily Telegraph , The Observer , The BIg Issue , Guardian Colour section , Pacific Standard , and an article by David Ropeik in the Big Think .

There is a video from the RSA featuring both the authors, and a Guardian podcast with an extensive interview with both of us.


[This needs bringing up-to-date.]

Here is a list of all my presentations since October 2007, including appearances at Cambridge Science Festival, Cheltenham Science Festival, British Science Festival and Hay Literary Festival.

In over 400 talks since October 2007, audiences total around 51,000 (up to June 2014), including around 20,000 school students.

Recent presentations include:

Many of my talks have appeared online, although I have not watched most of them and so can't comment on their quality. A sample is given below.

External work

In the past I have acted as a paid statistical consultant to a variety of organisations, including the Healthcare Commission, World Anti-Doping Agency, Novartis, and GlaxoSmithKline. I now occasionally accept fees for giving talks, which I donate to this excellent charity - the Karuna Trust.
