In the middle of a discussion about the pros and cons of statins, Sir Rory Collins, the head of clinical trials at Oxford University, noted that If you want a career in medicine these days you're better off studying mathematics or computing than biology. A report on BBC adds: It is a nice one-liner, but I didn't think much more about it until a few days later, when I found myself sitting in a press conference to mark the launch of a new initiative on cancer. Rubbing shoulders on the panel with the director of the Institute of Cancer Research, Professor Paul Workman, was a scientist I didn't recognise, but it soon became clear this was exactly what Sir Rory had had in mind. Dr Andrea Sottoriva is an astrophysicist. He has spent much of his career searching for Neutrinos -- the elusive sub-atomic particles created by the fusion of elements in stars like our sun -- at the bottom of the ocean, and analysing the results of atom smashing experiments with the Large Hadron Collider at Cern in Geneva. "My background is in computer science, particularly as it applies to particle physics," he told me when we met at the ICR's laboratories in Sutton. So why cancer? The answer can be summed up in two words: big data. What Dr Sottoriva brings to the fight against cancer is the expertise in mathematical modelling needed to mine the vast treasure trove of data the information revolution has brought to medicine. "The exciting thing is that we can apply all the new analytical techniques we've developed in physics to biology," he says. "So we have all these new quantitative technologies that allow us to process an enormous amount of data, and all of a sudden we can start to apply that to implement the paradigm of physics in biology."
