Professor Jane Clarke has had a fascinating double career. Having been a science teacher for many years, she didn’t start her research career until she was 40. Today she is a world-leading expert in molecular biophysics and, in particular, in how protein molecules in the body fold up into elaborate 3D structures, that only then enables them to carry out their roles. How they do this has been one of the fundamental questions in biology and the key to combating some of our most challenging diseases, caused by the misfolding of proteins.Jane talks about her journey, from Tottenham schoolteacher to Cambridge Professor and Fellow of the Royal Society, and how, despite the obstacles she’s encountered along the way, she’s always been driven by her passion to understand the mystery of the machinery of life.Producer: Adrian Washbourne
