Ruth Williams

Ruth is a freelance journalist. Before freelancing, Ruth was a news editor for the Journal of Cell Biology in New York and an assistant editor for Nature Reviews Neuroscience in London. Prior to that, she was a bona fide pipette-wielding, test tube–shaking, lab coat–shirking research scientist. She has a PhD in genetics from King’s College London, and was a postdoc in stem cell biology at Imperial College London. Today she lives and writes in Connecticut.
