The SciFest 2025 National Final, held in Marino Conference Centre in Dublin in November, was attended by students from every corner of Ireland with 51 students from 31 schools qualifying to participate this year. Students secured their place at the National Final by winning one of the top awards at the 15 regional SciFest fairs earlier in the year.
This year’s programme also featured five international projects from students in Sri Lanka and South Africa, further extending the global network of SciFest.
Zack O’Leary from Co. Kildare representing Clongowes Wood College won the overall title of SciFest STEM Champion 2025 for his project M.A.N.T.I.S “Muon Analysis for Non-Invasive Tomography and Image Simulation”. Zack will go on to represent Ireland at the Regeneron International Science and Engineering Fair (ISEF) in Phoenix, Arizona next May.
Thanks to the generous support of Regeneron three projects will represent Ireland at the Regeneron ISEF 2026 in Phoenix. In addition to SciFest STEM Champion 2025, Zack, the students travelling to the United States include:
Addison Carey, Celbridge Community School, Co. Kildare, for her project, "Advancing Post-Quantum Lattice-Based Cryptography by Developing Efficient Shortest Vector Problem Approaches" and
Ronan Lyons, Lanesboro Community College, Lanesborough, Co. Longford, who also won the Boston Scientific Medical Devices Grand Award, for his project, "Capill: Compliance Aid Promoting Independent Long-Term Living."
