Staff Profile

I’m a surgeon and researcher based in Newcastle, working on how artificial intelligence can make organ transplantation safer, fairer, and more efficient.

Supported by fellowships from the NIHR and Royal College of Surgeons of England, my research combines clinical insight with methods from computer vision, statistical modelling, and high-performance computing to develop tools that learn from large-scale datasets.

My PhD, under the supervision of Professor Colin Wilson, and Professor Neil Sheerin, focuses on how AI can quantify organ quality and reduce the uncertainty that often shapes clinical judgement.

I’m motivated by the belief that technology should not only make medicine smarter but also fairer, ensuring that every decision has the best possible chance to improve patient care.
