Siya poddar: How a 17-Year-Old Built a Shield for the World

Meet Siyaa, a 17-year-old researcher and environmental advocate from Arizona who’s quite literally turning science into a shield for communities. She created RADAR, a material that changes colour to detect invisible pollutants like uranium and silica, a breakthrough that could transform how vulnerable communities safeguard their health.But what’s truly remarkable about Siyaa isn’t just the innovation or the awards she’s already earned,  like the Regeneron Young Scientist Award – it’s the kind of person she is. She’s one of the sweetest, most compassionate young minds you’ll ever meet. Despite studying in a school without state-of-the-art labs or fancy equipment, she refused to let limited resources limit her imagination. Instead, she persevered, working through setbacks, improvising with what she had, and keeping her focus on why she started: to make science accessible and impactful for those who need it most.Siyaa’s story is as much about resilience and kindness as it is about discovery and it’s a reminder that the best science is rooted in both intellect and heart.
