Four students from Greenwood High International School have won a gold medal at the IRIS National Fair 2025–26, a pre-college STEM research competition.

Representing the school’s Sarjapur campus in Sarjapur, Gautam Mahesh and Rachvik Arora (Team 1), along with Youbin Duan and Aarush Mandala (Team 2), were recognised for two independent research projects in medical diagnostics and advanced imaging.

The IRIS National Fair, organised by the EXSTEMPLAR Education Linkers Foundation, brought together 75 student innovators from 12 states and 24 cities. The platform serves as India’s gateway to the International Science and Engineering Fair (ISEF) 2026, a global science competition for school students.

Gautam Mahesh and Rachvik Arora developed an AI-assisted biosensor designed to detect virulence and antibiotic-resistance mutations in Helicobacter pylori, a bacterium linked to gastrointestinal diseases. Their project integrates artificial intelligence with biosensor technology to support early and accurate mutation detection, with applications in treatment planning and antimicrobial resistance management. The team received a gold medal and advanced to the final selection round for international representation.

In a separate project, Youbin Duan and Aarush Mandala studied retinal imaging in their paper titled “Frequency Encoded Proton Electron Microscopy on the Retina”. Using physics-based simulation, they demonstrated how frequency encoding could enhance Two-Photon Excitation Fluorescence imaging by improving image quality while reducing exposure time. The findings indicate potential applications in ophthalmic diagnostics and vision science.

“We are proud of our students for their commitment to scientific research and their focus on addressing global challenges,” said Niru Agarwal, Managing Trustee of Greenwood High International School.
