Professor Donal Wall sat at a desk in front of the House of Commons committee, sharing his oral evidence

The School of Infection & Immunity's Professor Donal Wall has given expert oral evidence to the House of Commons Science, Innovation and Technology (SIT) Committee as part of its inquiry into the UK’s microbiome research landscape.

The SIT Committee, a key body in Parliament, is tasked with scrutinising the Department for Science, Innovation and Technology and ensures that policy decisions across government are grounded in robust scientific advice. 

As part of its Under the Microscope inquiry, the Committee issued a call for written submissions exploring a wide range of scientific and technological themes. From over 330 submissions, just six individuals were invited to present oral evidence in person, including Sii Head of Bacteriology Professor Wall, on Tuesday, 1 July 2025.

Professor Wall provided an accessible overview of microbiome research in the UK, outlining its significance, current strengths, and the areas where additional support is needed for the UK to remain globally competitive, particularly compared to research efforts in Europe and the USA.

Drawing on local examples, he highlighted initiatives led from the University of Glasgow, including the BINGO group—an interdisciplinary collaboration between academics and clinicians focusing on inflammatory bowel disease—and the Glasgow University Microbiome Initiative, which brings together researchers across a variety of fields.

Reflecting on the experience, Professor Wall said: "It was an excellent opportunity to engage with MPs in a meaningful way about research.

"I'm hopeful they took on board some of the messages about the support required to ensure such research in the UK can realise its full potential.”

MPs will now consider the oral evidence presented, with the possibility of further sessions or follow-up inquiries to explore specific issues in greater detail.
