When Divaa Uthkarsha’s younger brother was diagnosed with Type 1 Diabetes, she was only 13, and the impact of that moment would shape the course of her life. Divaa began to notice something even more frightening than the disease itself: a system where thousands of children lacked access to life-saving insulin, care, and awareness. What started as a personal heartbreak became a determined call to action.

‍

At just 13, Divaa founded Project Surya, named after her brother, to fight the healthcare inequity faced by children living with Type 1 Diabetes in underserved communities. Since then, the student-led initiative has grown into a global movement operating across five countries. Project Surya has impacted over 450,000 lives, supported 2,100 children, distributed 8,000 vials of insulin, and built a network of more than 120 youth volunteers. Through medical camps, digital awareness, research, and direct care efforts, the project challenges both social stigma and systemic neglect.

‍

Divaa’s journey from caregiver to changemaker has earned her both national and international acclaim. She is one of the Top 10 Global Finalists for the Chegg.org Global Student Prize, selected from over 11,000 applicants worldwide, and a recipient of the Diana Award, one of the highest honors for young people creating social impact. Her work has been featured by major media platforms such as CNN-News18, Femina, and The Times of India, and she has been invited to speak at global stages including the United Nations Headquarters in New York.Beyond the numbers and awards, Divaa is driven by a clear belief that empathy, when backed by action, can transform lives. She co-authored Asia’s first youth-led PubMed-indexed paper on community health worker interventions for childhood diabetes and continues to advocate for healthcare systems that center dignity, accessibility, and lived experience. Divaa is on a mission to make access to quality health care a human right once again and not just a privilege for the affluent.

Sirish Subash is a young innovator who is passionate about using science to solve real-world problems. Ever since he was little, he was curious about how things worked. That curiosity led him to science, where he found both answers and more questions. As he learned more about the challenges people face—like climate change and food safety—he started to see how science could offer real solutions. This is what inspired him to start building and sharing tools that help people better understand and protect the world around them.

‍

In 2024, Sirish was named America’s Top Young Scientist after winning the 3M Young Scientist Challenge for his invention, PestiSCAND. PestiSCAND is a small, handheld device designed to detect pesticide residues on produce, helping people stay safe from harmful chemicals in their food. Pesticide residues are hard to remove with just water, and are linked to many health problems. With PestiSCAND, Sirish hopes to give people the power to make informed decisions about what they eat.

‍

Sirish also believes strongly in the power of science communication. He has written two books to help young people better understand science. His first book, Carbon Block Puzzle, is a beginner-friendly guide to climate change—explaining what it is, why it matters, and what we can do. His second book, Biochemistry the Fun Way, is a graphic novel that introduces biochemistry in a fun and simple way. Sirish hopes these books inspire kids to be curious and see science as something they can do, too.

‍

Alongside writing and inventing, Sirish has spent years participating in science fairs, speaking events, and other STEM programs. These experiences have helped him gain skills in research, building projects, and explaining scientific ideas to different kinds of audiences. He has also learned how to stay focused through long and difficult challenges, and how to turn ideas into real things that can help people.

‍

As he looks to the future, Sirish plans to keep working on science projects that make a difference. He is interested in exploring fields like biotech, physics, and math, and continuing to share science in ways that are clear, fun, and useful for everyone.

Dhruv Chaudhary is one of the creators and driving forces behind Thermavault, a breakthrough thermal storage solution designed to solve one of the most overlooked problems in global healthcare, cold-chain failure. As a high school senior with a passion for engineering and impact-driven innovation, Dhruv’s journey began not in a lab, but in the field where he witnessed firsthand the devastating consequences of temperature-sensitive vaccines and medicines going to waste in rural clinics due to unreliable electricity. What started as a frustrating observation quickly transformed into a personal mission: to build a system that didn’t depend on infrastructure to save lives.

‍

The idea of Thermavault emerged from this urgency. Dhruv began prototyping a thermal storage box that could keep life-saving medicines cold without power, using principles of conductive materials, chemical reactions, and insulation. After countless iterations and failures, he developed a stackable copper-core container with a fluid-based cooling jacket powered by a safe, reusable salt mixture. His design could reliably maintain temperatures as low as 3°C using a reusable salt reaction, and down to -10°C with a single-use mix that is perfect for both short-term vaccine storage and deeper cold-chain use cases like organ transport.

‍

Beyond the engineering, Dhruv is working to ensure Thermavault is usable, modular, affordable, and durable enough to survive real-world field conditions. His journey has included field testing in real hospitals to complete reworks of the design within just 6 months of initiation.  Thermavault extends far beyond awards or recognition and acts as a gateway to equitable healthcare access, especially in underserved regions.

‍

Today, Dhruv stands not just as a student innovator but as a rising voice in sustainable technology. His work with Thermavault reflects a belief that science should be actionable, empathetic, and built for the people who need it most.

Marta Bernardino is a 19-year-old Portuguese inventor whose field of expertise is developing robots to scale nature conservation efforts.

‍

To date, Marta records a 10-year background in self-taught robotics, having built her first robot at the age of 9 using recycled plastic and motor fans. Growing up in the countryside, she experienced the drastic change of ecosystem destruction, from beach pollution to deforestation. So since then, she has used her robotic skills, combined with a passion for problem-solving, to develop solutions for her community. Today, she focuses her work on nature conservation and protection, and is the youngest nominated conservation roboticist explorer at *National Geographic*.

‍

Her portfolio in conservation robotics ranges from designing a surface water robot to combat offshore plastic pollution to co-developing a seaweed monitoring robotic system that tracks biomass growth and water quality. In a nutshell, her work focuses on developing robotic technology that restores or protects ecosystems—whether as proprietary work, consulting projects, or corporate collaborations—always with a focus on long-term environmental impact. Notably, her work includes **SONDA**, an autonomous buoy she co-developed that uses beam technology and noise-cancelling techniques to eliminate noise pollution in marine protected areas, enhancing fish fertility and conserving cetacean communication.

‍

She is also the co-founder of Trovador, a Portuguese startup developing autonomous reforestation robots for hazardous, remote, and degraded locations. As CEO of Trovador, she co-leads the mission of restoring her home country’s forests and reviving native canopies around the world. Trovador has been recognized by National Geographic and was nominated as a Leader in Sustainable Robotics by euRobotics.

Sebastião Mendonça is a 19-year-old tech innovator and social impact leader from Portugal, using robotics and space tech to reimagine how we protect and restore nature.

‍

He’s the co-founder and CTO of Trovador, a robotics-for-reforestation startup developing autonomous legged robots that plant trees in steep, fire-damaged terrain, restoring land once considered unrecoverable. The project’s impact quickly gained global attention, with its founding duo becoming the youngest ever recognized with the Leadership in Robotics for Sustainability award and invited to present Trovador in over 10 countries across 4 continents.

‍

Alongside the robot, Sebastião designed a satellite-guided tool that maps post-fire zones where reforestation will have the greatest ecological impact, helping land managers prioritize limited resources and make the most of every euro and every seed. The project also ranked in the top 1% of ~7,000 global participants in the Non-Trivial Research Fellowship. This dual approach – from microsite to macro-map – reflects Sebastião’s belief that restoring nature demands both precision and perspective.

‍

His journey into STEM and space began early, earning medals in Physics, Chemistry, Astronomy, and also Philosophy Olympiads. He went on to represent Portugal and Europe in international competitions, even leading a global team at NASA’s Kennedy Space Center. At just 17, he became one of the few people to ever float in zero gravity, after winning a national astronaut-style selection program that culminated in a parabolic flight alongside astronauts from the European Space Agency (ESA).

‍

Since then, he’s worked on satellite-ground communication systems for a satellite monitoring Portugal’s coastal waters, and took part in a rocket launch campaign with ESA in the Arctic, launching a rocket to study flight dynamics and atmospheric conditions – reaffirming the power of space technology to solve problems here on Earth.

‍

But his work doesn’t stop at code or circuitry. For the past four years, Sebastião has been leading educational and social impact programs in Lisbon, focusing on young people from underserved backgrounds. Through a volunteer-run initiative, he organized monthly activities to spark curiosity and confidence, from telescope nights and robotics workshops to philosophy circles and tree-planting days… So far, these programs have reached hundreds of students, helping them explore new worlds, both outside and within.

‍

Behind every robot and satellite is one of those kids, the kind who got lost folding carefully crafted paper planes and exploring every hillside, tree, and trail their country had to offer. Sebastião’s work is his answer to that wonder – a way to ensure the world stays just as full of it.
