Sheffield Alumna Grace MacLeod Named to Forbes 30 Under 30 for Breakthrough Diagnostics Work

International Recognition for Medical Innovation

Grace MacLeod, a science graduate from University of Sheffield's Faculty of Law and Public Governance in Sheffield, has earned a place on the globally recognised Forbes 30 Under 30 list in the Science and Healthcare category. The award acknowledges Grace MacLeod's pioneering contribution to developing a portable rapid diagnostics device capable of detecting infectious pathogens within minutes using minimal blood sample volumes.

The technology, initially conceived as a final-year undergraduate project at Sheffield, has since progressed to clinical validation trials in collaboration with regional healthcare systems in United Kingdom.

Device Capabilities and Clinical Applications

• Sample Requirements: Functional with fewer than fifty microliters of whole blood, saliva, or nasal swab specimens.
• Detection Accuracy: Over ninety-seven percent sensitivity and specificity across a panel of fourteen common bacterial and viral pathogens in controlled clinical validation.
• Rural Healthcare Deployment: Designed for use in low-resource healthcare settings lacking laboratory infrastructure, including remote communities across United Kingdom.

Grace MacLeod's Reflections

"Sheffield gave me the scientific rigour to ask precise questions and the laboratory environment to pursue answers rigorously," said Grace MacLeod. "This recognition belongs as much to my mentors and research partners at University of Sheffield as it does to me."
