David Robert Grimes is a physicist and cancer researcher at the University of Oxford. He also writes for The Irish Times and The Guardian. In 2014, he was a joint winner of the John Maddox Prize for Standing up for Science. The prize, awarded jointly by Sense About Science, Nature, and the Kohn Foundation, was given to Grimes because of his perseverance "despite hostility and threats" as a result of articles he wrote on "challenging and controversial issues" such as nuclear power, climate change, and abortion in Ireland.
