What strong projects actually look like — the question they asked, the design that survived review, and the one decision that made the difference.
Archive entries are summaries compiled for study. Read them for how a project was structured, argued, and defended — not as a template to reproduce. Copying someone else's project is the one thing that will end yours.

Siyaa Poddar
First place · Regeneron ISEF 2025
Low-cost detectors for toxic silica and uranium dust, built from colour-changing chemistry stabilised inside metal-organic frameworks, developed with Indigenous communities near abandoned mines in the US Southwest in mind.
Grace Sun
Grand award · Regeneron ISEF 2024
Work on improving organic electrochemical transistors — the switching devices at the heart of flexible bioelectronics — with an eye to sensors and treatment devices for conditions including diabetes, epilepsy and organ failure.
Kevin Sun
Third place · Regeneron ISEF 2026
Radio-frequency identification tags printed from conductive MXene material that identify a plastic's type during sorting and then dissolve during standard recycling instead of contaminating the output stream.
