Overview
Postdoctoral researcher in Operational Research at Cardiff University, working alongside Cardiff and Vale Health Board. My research focuses on the development of mathematical models and algorithms to improve the planning and delivery of healthcare services. In my current role, I am embedded within a local NHS health board, working on projects that aim to improve the efficiency and effectiveness of the NHS.
