US researcher Siddhartha Roy has won the Maddox Prize for standing up for science after leading a study that identified a high risk of lead contamination in the drinking water in Flint, Michigan. The environmental scientist from Rutgers University–New Brunswick received the accolade at a ceremony hosted by the Royal Society in London.
Siddhartha Roy Wins Maddox Prize for Flint Water Research
Roy co-led a scientific team that uncovered high lead contamination levels in Flint, contradicting official state and federal assurances that the municipal water was safe for residents. The discovery triggered a national scandal, culminating in a class action settlement totalling hundreds of millions of dollars and driving major infrastructure and policy reforms. Judges praised Roy for consistently placing the dignity and well-being of the Flint community ahead of his own comfort.
Following the initial findings, campaign groups utilized the team’s discovery to claim that lead poisoning had caused widespread brain damage among children in the area. However, when Roy analyzed the data independently, he found no notable difference compared to the rest of the state. He reported that media characterisations labeling healthy children as brain-damaged fostered lower expectations and poor mental health outcomes—a phenomenon he identified as a nocebo effect. Consequently, Roy faced direct threats from invested pressure groups.
Special Commendation Awarded to Gaza Public Health Researcher
Samer Abuzerr, a public health specialist at the University College of Science and Technology Khan Yunis, received a special commendation from the judging panel. Abuzerr conducted his research in Gaza despite the physical destruction of his university and severe resource scarcity. Judges highlighted his work tracking the resurgence of polio among children, which contributed directly to the 2025 humanitarian ceasefire.
Other shortlisted nominees included neuropsychologist Sallie Baxendale from UCL, who investigated concerns regarding puberty blockers and adolescent brain development as the sole Briton shortlisted. India-based liver specialist Cyriac Abby Philips was recognized for highlighting patient harms caused by traditional medicines, while clinical psychologist Arna Mitchell challenged claims of systemic racism against Māori heritage people in psychology. In the early career category, Mónica Guzmán-Rojo of the Universidad Católica Boliviana won for advocating on behalf of Indigenous and rural communities against powerful land interests.
Sense about Science Defends Research Independence in Polarized Times
Tracey Brown, chief executive of Sense about Science, which organizes the Maddox Prize, emphasized that researchers must retain the ability to question findings openly. “We live in more polarised times in many parts of the world, and the nominations for the Maddox Prize show that we must make a renewed case for the importance of space to enquire, even where we have strong views,” Brown stated.
Brown added that public protection of independent research spaces prevents outside interests from taking sides. “We must protect that space from taking sides and from powerful interests, so that researchers continue to ask searching questions and feel confident in telling us what they find,” she said. “This year’s Maddox prizewinner shows us very clearly why communities need that access to clear and honest research findings.”
