The University of Johannesburg is celebrating the achievements of two Grade 11 learners from the UJ Academy Maths, Science and ICT School of Specialisation in Gauteng, who were finalists at the 2026 Eskom Expo for Young Scientists International Science Fair (ISF).
Held from 29 September to 2 October 2026 at the Birchwood Hotel and OR Tambo Conference Centre in Johannesburg, the ISF brought together young scientists from South Africa and abroad to present their research to judges, STEMI professionals and fellow participants.
Rudra Patel was a finalist in the Plant Sciences category with his project, “Machine Learning Optimisation of Invasive Alien Plant Extracts as Sustainable Biostimulants for Crop Growth.” His research combined machine-learning techniques with laboratory experiments to investigate how different concentrations of Lantana camara extract affect wheat growth.
His work earned him a Gold Medal, as well as the Top Senior Scientist Award in Plant Sciences and the 2026 Top Senior Scientist Award, accompanied by a R75 000 cash prize.
The research demonstrated the potential for computational methods to complement experimental science in investigating applications for invasive alien plant material. The Eskom Expo noted that while Rudra’s machine-learning models identified general concentration-dependent trends, further standardised experimental data and analysis would be required before reliable agricultural applications could be established.
Rudra’s achievement follows months of research, experimentation and refinement, culminating in the opportunity to present and defend his work at one of South Africa’s leading platforms for young scientists.
Fellow Grade 11 learner Matome Tjpana was also a finalist at the ISF, competing in the Physical, Astronomy and Space Sciences category.
Matome presented his project, “Design and Performance Evaluation of a Bio-Composite Sound Absorbing Wall Panel for Low Cost Housing.” His research explored the development and performance of bio-composite materials for sound absorption, with potential applications in the development of more affordable and effective housing solutions.
The achievements of Rudra and Matome reflect the opportunities available to UJ Academy learners to engage with research and apply scientific thinking to real-world challenges.
“Rudra and Matome’s achievements are a source of great pride for the University of Johannesburg and the UJ Academy. Their success reflects what is possible when young people are encouraged to pursue knowledge, think innovatively and apply their learning to real-world challenges. Through opportunities such as the Eskom Expo ISF, our learners are developing the confidence, research skills and critical thinking needed to become the innovators and problem-solvers of the future. We congratulate Rudra and Matome on this outstanding achievement and look forward to seeing them continue to grow and make an impact through their academic journeys,” said Prof Nadine Petersen, Executive Dean of the UJ Faculty of Education.
The UJ Academy Maths, Science and ICT School of Specialisation is a Gauteng Education Department school that provides learners with specialised opportunities in mathematics, science and information and communication technologies. The University of Johannesburg contributes to the school’s development, supporting opportunities that strengthen learners’ academic development and create pathways towards higher education.
The 2026 Eskom Expo ISF recognised outstanding young scientists with 25 Gold, 100 Silver and 111 Bronze medals across the competition categories. Selected participants will also have opportunities to represent South Africa at international science fairs and programmes, with opportunities expected in countries including Taiwan, India, Tunisia, China, the United States, Indonesia, Ireland and Türkiye.
Beyond the awards, participation in the ISF gives young researchers an opportunity to communicate and defend their research, engage with fellow scientists and STEMI professionals, explore career pathways and build networks that can support their future development.
For Rudra and Matome, the 2026 ISF marks another step in their development as young researchers. Their achievements demonstrate the value of nurturing curiosity and research skills at school level and encouraging young people to use science and innovation to explore solutions to real-world challenges.
The University of Johannesburg congratulates Rudra and Matome on their achievements and wishes them well as they continue their academic and research journeys.
