Dr Alexandra Freeman is Executive Director at the Winton Centre for Risk and Evidence Communication. Prior to joining the Winton Centre in 2016, Dr Alex Freeman had a 16 year career at the BBC, working on series such as Walking with Beasts, Life in the Undergrowth, Bang Goes the Theory, Climate Change by Numbers, and as series producer of Trust Me, I’m a Doctor. Her work won a number of awards, from a BAFTA to a AAAS Kavli gold award for science journalism. In addition, Alex worked with associated content across a range of other media – designing websites, games, formal learning resources and social media content – to bring science to the widest possible audience. She is particularly interested in helping professionals such as doctors, journalists or legal professionals to communicate numbers and uncertainty, and in whether narrative can be used as a tool to inform but not persuade. She is an advocate of Open Research practices and the reform of the science publishing system.

Professor Sir David Spiegelhalter is Chair of the Winton Centre for Risk and Evidence Communication in the University of Cambridge, which aims to improve the way that statistical evidence is used by health professionals, patients, lawyers and judges, media and policymakers. He advises organisations and government agencies on risk communication and is a regular media commentator on statistical issues, with a particular focus on communicating uncertainty. His background is in medical statistics, and in addition to more than 200 refereed publications, and has authored and co-authored several books. He works extensively with the media, and presented the BBC4 documentaries “Tails you Win: the Science of Chance”, the award-winning “Climate Change by Numbers”, and in 2011 came 7th in an episode of BBC1’s Winter Wipeout. Sir David was elected Fellow of the Royal Society in 2005 and knighted in 2014 for services to medical statistics. He was President of the Royal Statistical Society for 2017–18.
