Dr. Elizabeth Williams

Research Associate

-Ph.D--MMath-

Hello and Welcome! 😀

I'm Elizabeth, and I'm currently working as a Research Associate at the School of Mathematics at Cardiff University.

About me

Research Interests

I am interested in the application of Operational Research to healthcare services. 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 healthboard, working on projects that aim to improve the efficiency and effectiveness of the NHS.
