A school student's research combines machine learning and plant science; Rudra Patel wins three awards at 2026 Eskom Expo A Grade 11 student from South Africa has combined machine learning and laboratory experiments to investigate whether an invasive plant could have potential applications in agriculture.
Rudra Patel, a learner at the University of Johannesburg (UJ) Academy Maths, Science and ICT School of Specialisation, received three awards at the 2026 Eskom Expo for Young Scientists International Science Fair.Patel was recognised with a Gold Medal, the Top Senior Scientist Award in Plant Sciences and the overall 2026 Top Senior Scientist Award.
The latter came with a cash prize of R75,000 (approximately ₹4.1 lakh).
His research examined how extracts from Lantana camara, an invasive alien plant, affected wheat growth at different concentrations.How machine learning featured in the research Titled “Machine Learning Optimisation of Invasive Alien Plant Extracts as Sustainable Biostimulants for Crop Growth”, Patel's project brought computational methods and experimental science together.He used machine-learning techniques alongside laboratory experiments to investigate the effects of different concentrations of Lantana camara extract on wheat.
The research explored whether material from an invasive plant could be studied for possible use as a biostimulant, a substance that can support plant growth.
The approach offered a way to examine patterns in the relationship between extract concentration and wheat growth.
However, the findings are still at the research stage.
The Eskom Expo noted that while Patel's models identified general concentration-dependent trends, more standardised experimental data and analysis would be needed before reliable agricultural applications could be established.Another Grade 11 student explores affordable housing Patel was not the only learner from the UJ Academy to reach the international science fair.
Fellow Grade 11 student Matome Tjpana was also a finalist, competing in the Physical, Astronomy and Space Sciences category.Tjpana presented a project titled “Design and Performance Evaluation of a Bio-Composite Sound Absorbing Wall Panel for Low Cost Housing”.
His research examined the development and performance of bio-composite materials for absorbing sound, with potential applications in more affordable housing.Both learners presented their work at the 2026 Eskom Expo International Science Fair, held from September 29 to October 2 at the Birchwood Hotel and OR Tambo Conference Centre in Johannesburg.
The event brought together young researchers from South Africa and other countries to present their projects to judges and professionals working in science, technology, engineering, mathematics and innovation.More than 230 medals awarded at the science fair The 2026 competition recognised young researchers with 25 Gold, 100 Silver and 111 Bronze medals across different categories.
Selected participants are also expected to get opportunities to represent South Africa at international science fairs and programmes in countries including Taiwan, India, Tunisia, China, the United States, Indonesia, Ireland and Türkiye.The UJ Academy Maths, Science and ICT School of Specialisation is a Gauteng Education Department school that provides specialised learning opportunities in mathematics, science and information and communication technologies.
The University of Johannesburg supports the school's development and helps create pathways for learners towards higher education.According to the university, participation in the science fair gives students an opportunity to present and defend their research, interact with other young scientists and STEM professionals, and explore possible academic and career pathways.
