Husband / Spouse
Hannah Fry is married as of 2025. Her husband, Phil, keeps a low profile and doesn’t work in television or academia, and the couple have two daughters. He appeared on screen briefly in her 2021 BBC Two documentary Making Sense of Cancer with Hannah Fry, which followed her own diagnosis and treatment — some of the most personal footage she’s ever filmed, including the hours before her radical hysterectomy.
Fry has spoken openly about how having young children shaped her attitude to risk, statistics and medical decision-making. She was diagnosed with cervical cancer in 2021 at the age of 36, after what she’s described as a textbook example of how badly people understand probability — including, briefly, herself. She also lives with lymphoedema in one leg as a result of the surgery and has campaigned for better awareness of the condition.

Hannah Fry’s Facts
She delivered the 2019 Royal Institution Christmas Lectures, titled “Secrets and Lies: The Hidden Power of Maths,” becoming one of the few presenters to take on all three lectures solo.
The 2018 BBC Four experiment Contagion! collected movement data from around 30,000 volunteers via a smartphone app. That dataset was later used in genuine academic modelling of COVID-19 spread in Britain.
She won the Christopher Zeeman Medal in 2018, awarded by the London Mathematical Society and the Institute of Mathematics and its Applications for communicating maths to the public.
Her PhD research had nothing to do with statistics or data science — she worked on the fluid dynamics of thin films and pattern formation.
Hello World was shortlisted for the 2018 Royal Society Insight Investment Science Book Prize and has been translated into more than 20 languages.
She hosted DeepMind: The Podcast, giving her unusually close access to the Google-owned AI lab years before the current AI boom.
Her early academic work at UCL’s Centre for Advanced Spatial Analysis used mathematical models to study the 2011 London riots.
In 2024 she became the first holder of the Professorship of the Public Understanding of Mathematics at Cambridge, a chair created specifically with her kind of work in mind.
