Job

I am now Emeritus Professor of Statistics at the University of Cambridge.

From 2016 until 2023 I was Chair of the Winton Centre for Risk and Evidence Communication. This Centre, generously funded by the David and Claudia Harding Foundation, was based in the Department of Pure Mathematics and Mathematical Statistics in Cambridge, and was 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.

The Art of Statistics

The Art of Statistics is a Pelican book published by Penguin in March 2019 in the UK, and by Basic Books in the US in September 2019 - the books are identical apart from the subtitle and cover. The UK Pelican paperback was published in February 2020. This is its UK 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), and here is its US Amazon site.

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

There have been articles about it by Hannah Fry in the New Yorker , and by myself in Aeon Magazine and Scientific American .

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

Coincidences

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.

Immodest stuff

See my Google Scholar page for the top citation-earners. I am among the many ISI Highly Cited Researchers.
Google Scholar's list of top-cited statisticians in September 2020 had me about 26th in the world with around 126,000 citations (although there do seem to be some high-ranking 'statisticians' who seem more like particle physicists..) I hover around 8th when it lists biostatisticians. My citations include some medical papers in which I am one of many authors.
2017-2018: President of the Royal Statistical Society.
2015: I am the reigning (first and only) World Champion in Loop, the version of pool invented by Alex Bellos that is played on an elliptical table with a single pocket in the baize - more like a putting green than a pool table. Alex describes the principles in detail on the official Loop page.

Me in action at the Port Eliot Festival where I won the Loop championship - this was done using a mixture of mathematical insight, a little skill arising from a mis-spent youth, and a huge dose of luck.
2014: Knight Bachelor in the Queen's Birthday Honours List
2013: Honorary Fellow of the Royal College of Physicians
2013: Fisher Memorial Lecture, St Andrews University.
2013: Honorary Doctorate of Science from the University of Bath.

Media

Newspaper and magazine articles

I work closely with the Science Media Centre, receiving press releases under embargo on health stories with substantial statistical content, and having the opportunity for comments to be distributed to journalists. This leads to frequent quotes appearing in mainstream media, often on the topic of relative and absolute risks. Full articles include -

2016: Observer article: Our nine-point guide to spotting a dodgy statistic

Some older articles are listed here.

I have been a guest columnist in the Times on the risks of ecstasy and horse-riding, swine flu, Paul the Octopus (all behind a paywall) and other topics, the Guardian on uncertainty in forecasting, and New Scientist on over-reaction to risk.

Online articles

I have also written popular articles and blogs, with some highlights including:

2009: BBC Online Choose the yum and risk the yuk? ($>$ 300,000 hits)

2010: Guardian article: The myth of meaningful coincidence

2012: BBC Online Will I live longer than my cat? (which I did, the cat sadly having died soon after the article was published) ($>$ 300,000 hits)

2017: Medium article How dangerous is burnt toast?

2018: Medium article The risks of alcohol - again

Radio

Numerous appearances on Radio 4 programmes such as Today, More or Less , You and Yours, The Investigation, Analysis, PM and many others.

2013-2019: Three appearances with Brian Cox and Robin Ince on Radio 4's The Infinite Monkey Cage still available on Iplayer., including the extraordinary 100th edition, which was also televised.

June 2013: I featured in an episode of The Life Scientific hosted by Jim Al-Khalili, still available on Iplayer.

November 2013: I fronted an investigation into the PISA statistics comparing education systems around the world, which is now available on Iplayer.

Television

2019: Extensive interview about The Art of Statistics with Christiane Amanpour on CNN's Amanpour

2019: On the panel for an edition of BBC1's Politics Live

I was one of the three presenters for the BBC4 documentary Climate Change by Numbers first shown in March 2015, and repeated at odd times since.

I fronted Tails you win: the science of chance produced by Wingspan Productions and first shown on BBC4 on 18th October 2012. You might be able to see it on Youtube here, unless it's been taken down. The details of the numbers in the programme are given here.

As mentioned above, I was seventh in an episode of BBC1's Winter Wipeout , attracting my biggest ever audience in the millions. Possibly my greatest achievement.

I also appeared on the BBC4 documentary The Joy of Stats fronted by the wonderful Hans Rosling, the brilliant BBC2 Horizon programme To Infinity and Beyond which featured the infinite monkey and typewriter problem, and discussing homeopathy on Professor Regan's Medicine Cabinet , Panorama Why are Gambling Machines Addictive? playing on a fixed-odds betting terminal,

I've been live on Newsnight a few times, including facing Jeremy Paxman - he was charming.

And there is a clip here of me appearing with David Meade and doing some nice coin flips.

I also appeared in an episode of Morgan Freeman's Through the Wormhole , where I appear to have a very large object dropped on my head.

I have a rather meagre page on IMDB.

Science Media Centre

I work with the Science Media Centre in providing frequent comments for journalists writing stories about risks. I was on the panel that drew up guidelines for press reporting of science stories requested by the Leveson Inquiry

Twitter

I am @d_spiegel, with over 66,000 followers (October 2020), hugely increased over the Covid pandemic.

Education work:

2020- Member: Royal Society Mathematics Futures committee .
2016-2019 Member: Royal Society Advisory Committee for Mathematics Education (ACME)

I was an advisor to the Department for Education on the new syllabus for GCSE Mathematics, and possibly helped to get 'expected frequencies' into the Programme of Study: see this blog for some background and suggested material:Using expected frequencies when teaching probability.

Development of teaching materials on probability and risk for Key Stages 3 to 4 in conjunction with NRich (Jenny Gage) - this work was presented at the International Conference for Mathematic Education in Seoul, Korea in July 2012. Material is now available on NRich under the title Great Expectations: Probability through Problem Solving, and is currently being turned into a book to be published by Cambridge University Press.

I was on the Advisory Board for an MEI project producing material for the future Core Mathematics qualification, intended for those who get Grade C or above in GCSE Mathematics but do not go on to A level Maths. The MEI project is based on on the proposals by Professor Tim Gowers' blog on the type of maths that would be genuinely useful to students - here is a BBC article on the project. Funded by the Department for Education.

I was an advisor on the The Cambridge Mathematics Education Project (CMEP) which 'has the goal of helping to make sixth-form mathematics a rich, coherent and stimulating experience for students and teachers'. Funded by the Department for Education.

Talks to young people, for example through the Millennium Mathematics Project , University of Cambridge Widening Participation, Royal Institution Masterclasses, Cambridge Science Week, as well as talks in individual schools and colleges. In particular, Maths Inspiration can attract audiences of 1,000 in major West End theatres.

A column in Plus Magazine: see for example articles on the lottery, football premier league, surprises, how long you might live, and the probability that Obama would win the 2008 Presidential election.

Outreach collaborations:

2014-: Advisor for the Royal Statistical Society Ambassadors scheme, where 20 career-young statisticians have been selected to be trained for pubic engagement with statistics.

On the Advisory Board for the new Science Museum Mathematics gallery.

I was an advisor for the British Library's Beautiful Science exhibition, spoke at the opening ceremony and performed with Dame Sally Davies, Chief Medical Officer, at a public meeting on communicating health information.

I was joint curator of Risk Lab, an exciting exhibition combining art and experiments about risk hosted by the wonderful Science Gallery at Trinity College Dublin.

On the Board of the Royal Statistical Society Getstats campaign for improvement of statistical literacy: this includes developing a syllabus and material for journalism training on statistics and risk

Collaboration with the Met Office on an online randomised experiment of alternative ways of presenting probabilistic information on 5-day weather forecasts - over 8000 unique participants.

Worked with BBC Lab UK on a mass psychology experiment on risk perception and attitude: the Big Risk Test. Over 100,000 participants.

Academic collaborations:

Collaborator on a NIHR-funded project to research and improve the public understanding of surgical outcome data in congenital heart disease. This involves working with patient and media groups to test alternative presentation formats, and develop an animated web-site for the public and resulted in this wonderful website.

I was one of the original investigators in the University of Cambridge Behaviour and Health Research Unit (BHRU) which had a 5-year 3M Department of Health grant to "contribute evidence to national and international efforts to achieve sustained behaviour change that improves health outcomes and reduces health inequalities".

Jointly led a Mellon-Sawyer seminar throughout 2009-10 on Modelling Futures: Understanding Risk and Uncertainty. This ran through CRASSH and involved participants from History and Philosophy of Science, Geography, Judge Institute, Statistical Laboratory and many other Cambridge institutions from both the sciences and humanities, and was intended to shed light on the advantages and the limitations of formal models for prediction in the light of pervasive societal and scientific uncertainty.

Connections

If documentaries are included, my Bacon Number is 3, through Jim Al-Khalili (Horizon), Jonathan Ross (A night with the stars) to Kevin Bacon (Film 72)

My Erdos Number is 3 (through AFM Smith and Samuel James Taylor)

So my Erdos-Bacon Number is 6. Wikipedia only reports 8 people with lower Erdos-Bacon numbers, but I don't think these include documentaries.

Sex by Numbers

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.

Teaching

In 2017 and previous years I taught Part 1B Statistics - this is my teaching page.
I have previously taught Applied Bayesian Statistics in the Lent Term to Part III students.
In 2012 and 2013 I taught a 3-week graduate course on probability and statistics at the African Institute for Mathematical Sciences (AIMS) in Muizenberg, South Africa. The 2012 lectures were nicely edited to try and make them more coherent, and can be viewed here.
