When the water in Flint, Michigan, became contaminated with dangerous levels of lead, Dr Siddhartha Roy, then a third year PhD student, was part of the team of scientists who publicly contradicted state and federal claims that it was safe. He became a local hero until a new piece of research challenged the idea that children in Flint had been left permanently brain damaged by the crisis. His adherence to the evidence, no matter who it offended, has earned him the 2026 Maddox prize, which recognises individuals who stand up for science and evidence, despite challenges or hostility. He tells Ian Sample how he reflects on his experience in Flint, and why he lost friends as a result of his work there
How a scientist went from hero to traitor in a US water crisis - video
In short
As a third-year PhD student, Dr. Siddhartha Roy worked alongside a research team that disproved state and federal assurances regarding safe water in Flint, Michigan. While his initial findings earned him hero status, public sentiment turned hostile when later research challenged assumptions that local children suffered irreversible brain damage. Sticking to the scientific evidence ultimately alienated friends and cast Roy as a traitor. In an interview with Ian Sample, he addressed the heavy personal costs of defending his findings against public backlash.
