For over ten years, the NI Science Festival has been inspiring curiosity, sparking conversations and showcase how science shapes our world, and the 2026 programme is no different.
As part of this year’s programme, the festival is asking the question why science, bringing leading NI voices together to share real-word experiences and career paths in STEM subjects.
Taking part in an event to discuss careers, experiences, and passion for science and innovation will be NI’s Economy Minister Dr. Caoimhe Archibald, who graduated from Queen’s University, Belfast with a BSc in Molecular Biology and a PhD by research with a Department of Agriculture and Rural Development studentship.
Alongside her will be Professor Helen McCarthy, who is Northern Ireland’s first Chief Scientific and Technology Adviser. Focussing her research on novel non-viral delivery systems for nucleic acids and anionic small molecules, Professor McCarthy, who is the current Chair of Nanomedicine in the School of Pharmacy at Queen’s University Belfast, has published over 180 papers and is named inventor on over 35 patents.
Organised by NI Science Festival in partnership with Matrix, the fireside chat with Dr. Caoimhe Archibald and Professor Helen McCarthy will be hosted by Professor Victoria Simms who is chair of the NI Science Festival board.
Professor Simms says: “Science shapes our world and allows us to understand what is going on around us. The NI Science Festival year on year brings engaging and inspiring events, and I’m looking forward to chairing this fireside chat to hear real life experiences and why science is so important.”
Economy Minister Dr Caoimhe Archibald said: “Since 2015 the Science Festival has inspired thousands of young people and showcased the exciting career opportunities science and technology can offer. I’m delighted to take part in this discussion and to support an event that continues to encourage students to explore STEM which is vital to building a stronger economy and meeting the growing demand for STEM skills.”
The Executive’s Chief Scientific and Technology Adviser, Professor Helen McCarthy said: “I am delighted to take part in this year’s NI Science Festival which will showcase the opportunities offered by a career in STEM subjects. By encouraging more people to embark on a career in science and technology, we can unlock talent, drive innovation, and enhance the economic prosperity of the region.”
With a star-powered programme of world-class scientists, celebrity speakers and family-focused STEAM events, the NI Science Festival returns from 11-22 February to venues across Northern Ireland.
Why Science with Dr. Caoimhe Archibald and Professor Helen McCarthy will take place on Thursday 19th February in Crescent Arts Centre. For tickets or further details, visit www.nisciencefestival.com.
