Could an invasive plant have a useful role in crop research? That question helped Gauteng learner Rudra Patel earn the 2026 Top Senior Scientist Award and R75,000 at the Eskom Expo International Science Fair.

The Grade 11 learner at UJ Academy Maths, Science and ICT School of Specialisation investigated how different concentrations of Lantana camara extract affected wheat growth, combining computer modelling with laboratory experiments. 

His work also earned a gold medal. The fair took place from 29 September to 2 October 2026 at the Birchwood Hotel and OR Tambo Conference Centre in Gauteng. 

The Experiments Had Something to Teach the Computers

Rudra’s project explored whether machine learning could help identify patterns in plant responses and guide further experiments.

The models identified general trends linked to extract concentration.

However, the research also showed that reliable agricultural applications would need more standardised experimental data and analysis. His award recognises a research achievement, rather than a finished product ready for farmers. 

That distinction is part of what makes the project worthwhile: testing an idea includes finding where its predictions stop working.

UJ reports that Rudra spent months experimenting and refining his work before presenting and defending it at the fair. 

A Big Award, and a Sensible Plan

In an interview published by Eskom Expo, Rudra described his surprise when they announced his name.

“My mind went blank. It was almost like I couldn’t picture it happening.”

He credited his mentor, Lindiwe Maphalla, and the encouragement of friends and family with helping him persevere while balancing research and schoolwork. He also spoke about learning to manage his time more effectively. 

His plan for the prize money is practical: save it for future needs, potentially university.

Away from research, Rudra enjoys trying new things. He told Eskom Expo that his hobbies include baking and crochet, and that he has a life-sized emperor penguin among his creations. 

School Science With Room to Grow

Rudra was one of 316 young scientists from across South Africa, joined by 24 international participants, at this year’s fair. The programme gave learners opportunities to share their research with judges, other participants and science professionals. 

UJ Academy is a Gauteng Education Department school specialising in mathematics, science, and ICT, supported by the University of Johannesburg. 

The Bottom Line

Rudra’s project found both possibilities and limits. That is a good result for a young researcher: an award-winning investigation that leaves him with better questions to pursue next.
