Three young South African scientists are preparing to take their ideas to the world stage, as they represent the country at the prestigious Regeneron International Science and Engineering Fair in Phoenix, Arizona, from May 9 to 15.
The competition, regarded as the world’s largest pre-college science, technology, engineering and mathematics (STEM) fair, will bring together around 1,800 learners from more than 80 countries. For the South African trio, it is both a milestone and a moment of possibility.
They earned their place after achieving Gold and Silver medals at the Eskom Expo International Science Fair in 2025.
The learners representing South Africa are:
Tiro Moyo, 9, who attends Bryanston High School, Johannesburg.
Project: Predicting urban expansion and green space loss in Gauteng using satellite imagery and machine learning
Focus: Urban growth patterns, environmental sustainability, and evidence-based planning tools.
Gerhard Vosloo,17, who attends Parklands College, Cape Town.
Project: Machine-learning approach to detecting gravitational wave signals from LIGO data
Focus: Astrophysics, AI-driven signal detection, and improving real-time scientific analysis
Rudra Patel,16, who attends UJ Academy Maths, Science & ICT School of Specialisation, Johannesburg
Project: AI-based genomic optimisation for donor pig livers in human xenotransplant compatibility
Focus: Biomedical innovation, organ transplantation, and gene-editing prioritisation
Eskom Development Foundation Acting CEO, Mologadi Motshele, said the learners’ participation reflects the strength of South Africa’s emerging science ecosystem.
“Eskom, through its continued support of the Eskom Expo for Young Scientists, plays a vital role in preparing South African learners to compete on leading international platforms such as the Regeneron ISEF. The participation of local learners at this level reflects the strength of the country’s growing research and innovation ecosystem.”
She added that the organisation remains committed to developing future scientists and innovators beyond the classroom: “Eskom remains committed to developing future scientists, engineers and innovators by providing opportunities that extend beyond the classroom and onto the global stage.”
Eskom Expo Executive Director, Parthy Chetty, described the learners as an example of what young South African talent can achieve when given support and opportunity: “We proudly commend these three young scientists. Their curiosity, rigorous research, and collaborative spirit exemplify academic excellence and inspire other young South Africans.”
He emphasised that their success is also a collective effort: “We thank the mentors, families, and schools for nurturing talent and providing support. Their achievement demonstrates that bold questions and disciplined inquiry can open global opportunities.”
