David Spiegelhalter

Sir David Spiegelhalter is a statistician, risk expert, and Emeritus Professor of Statistics at the University of Cambridge. Known for making complex data accessible, he specialises in explaining risk, uncertainty, and statistical evidence to policymakers, professionals, and the public. A Fellow of the Royal Society and recipient of an OBE and a knighthood for services to medical statistics, David is one of the world’s most cited statisticians. His work focuses on helping society interpret numbers responsibly, particularly in areas where uncertainty shapes major decisions such as healthcare, public policy, and technology. He has served as President of the Royal Statistical Society and currently sits on the board of the UK Statistics Authority. His book The Art of Statistics became a bestseller, and he regularly appears on BBC programmes including Radio 4's More or Less and The Infinite Monkey Cage. Drawing on decades of experience analysing complex datasets, David helps organisations interpret uncertainty and communicate quantitative evidence responsibly. His presentations explore how statistics can inform better decision-making, how risk is often misunderstood, and how institutions can maintain trust when presenting uncertain information. Audiences learn practical techniques for questioning statistics they encounter in news stories, understanding probability in real situations, and recognising when data is being misused or misrepresented. David delivers these insights with clarity and humour, making technical concepts accessible without dumbing them down. Book David to help your audience think more critically about the numbers that shape their decisions.
