A 13-year-old has earned the distinction of being “America’s top young scientist” for 2026, taking first place in 3M’s prestigious Young Scientist Challenge. Raji Doshi, an eighth grader from Farmington, Connecticut, won the contest with an algae-based invention that could help save marine ecosystems.
She and nine other finalists aged 11-14 created their prototypes over the summer, each of them working with a mentor to develop their ideas. Raji won the $25,000 grand prize after the challenge’s final events on Oct. 12 and 13, presenting a natural system that addresses ocean acidification by increasing alkalinity and removing carbon dioxide.
Ocean acidification, which began during the industrial revolution, is primarily caused by the seawater absorbing carbon dioxide from the atmosphere. The change in PH reduces the abundance of carbonate ions: essential structures that many marine lifeforms, like corals and crustaceans, need to build their shells and skeletons.
“Raji’s project reminds us that when you’re passionate about something, you can use that interest to change the world,” her mentor, 3M product engineering specialist Deborah Isabelle, said in a press release. “She loves collecting seashells and was distressed that ocean acidification is starting to damage the seashells and the creatures that live inside them.”
The contest also recognizes two runners-up, who each received a $1,000 cash prize. The three honorees, all girls, point to promising changes in the STEM arena, where women have historically been underrepresented.
Seventh grader Aaisha Asif came in second place for her eco-friendly adhesive made from natural proteins; and ninth grader Sharvi Mahajan took third for her EEG-based device that tracks fatigue and predicts microsleep, alerting drivers and others in high-risk fields.
Looking at the full lineup of finalists, it’s clear the future of science is bright.
“The 3M Young Scientist Challenge highlights the incredible potential of young people to tackle real-world challenges through science,” said William Brown, 3M Chairman and CEO. “The talent and creativity displayed by this year’s finalists was exceptional, and we congratulate Raji on earning the title of America’s Top Young Scientist.”
