I’m from Cairncastle, County Antrim and graduated from Ulster University in 2025 with a First-Class Honours degree in Biomedical Engineering and a Diploma in Professional Practice with Distinction. My research interests are centred around applying engineering methods to clinical challenges, particularly within orthopaedics and medical device design.

During my first year with Tech4Health, I worked alongside an orthopaedic surgeon at Musgrave Park Hospital with the Trauma and Orthopaedic Research Charity (TORC) on a mini-project investigating the accuracy of bone resection cuts. This involved using 3D laser scanning and computational analysis to quantify resection errors in Total Knee Arthroplasty.

I spent my secondment with the same clinical team at TORC, building on this work by investigating the cutting jig used to guide bone resections. This project focused on identifying and understanding the main sources of error within the cutting process and how different aspects of the jig design can contribute to inaccurate cuts.

My PhD will build on both projects by developing methods to quantify these inaccuracies and investigate how the cutting jig can be improved to produce more accurate and repeatable bone resections. This will combine 3D laser scanning, computational analysis and programming with experimental testing and biomaterials research to explore new approaches to jig design.

Outside of my research, I enjoy hockey, flag football, running, sewing and going to concerts.
