About me

I am a scientist, writer and campaigner based in London, and author of Ageless: The new science of getting older without getting old. After a PhD in physics from the University of Oxford, I decided that ageing was the single most important scientific challenge of our time, and switched fields to computational biology. I worked at the Francis Crick Institute, using machine learning to decode our DNA and predict heart attacks using patients’ NHS medical records.

I’m now a full-time science writer and presenter. I’ve written for the Guardian, Telegraph and Wall Street Journal, am a regular expert on Impossible Engineering, and have featured on other shows on Discovery and the BBC. I also produce videos on my YouTube channel and give live talks ranging from lectures in schools to science stand-up at the Hammersmith Apollo. I’ve also campaigned about science funding as Chair of Science is Vital and creator of Scienceogram.
