Currently employed as a Teaching Associate supporting MSc modules on Statistics/Data Science and Operational Research.

Research interests are in applied and computational mathematics, specifically fluid dynamics, electromagnetics and disease transmission.

Previous name: Alexander Ramage


I grew up in Pembrokeshire, West Wales, and movd to Cardiff in 2010 when I began my undergraduate degree in Mathematics and its Applications here at the School of Mathematics. I've lived in Cardiff every since, undertaking my PhD off the back of my degree and comuting to Swansea when employed as a post-doc there. This is my second recent role at the School of Mathematics.

In 2021, I was married, and as a result changed my surname from Ramage to Pretty. My PhD thesis and my first paper are in my previous name.

Oct 2021 - present: Teaching Associate, School of Mathematics, Cardiff University

Feb 2021 - July 2021: Post Doctoral Research Associate, School of Mathematics, Cardiff University

I am currently a Teaching Associate supporting the MSc modules:

Foundations of Statistics and Data Science

Foundations of Operational Research and Analytics

I am on a 2 year contract to help support this popular and busy MSc.

Prior to this role I was also a Teaching Assistant on the MMath Fluid Dynamics course. During my PhD I held tutorials in a variety of first-year modules, including Elementary Differential Equations, Mechanics and Geometry as well as being involved in the Maths Support service.

I studied a PhD in fluid dynamics at Cardiff University under the supervision of Dr Chris Davies, entitled "Linear disturbance evolution in the semi-infinite Stokes layer and related flows". In this project we demonstrated that the Stokes layer - being the flow generated by the sinusiodal motion of a bounding plate - is subject to a form of absolute instability. The approach taken was a combination of direct numerical simulation of the linearised Navier-Stokes equations and solution of an eigenvalue problem arising from a linear stability analysis informed by Floquet theory.

Subsequently, I began a postdoctoral research position at Swansea University, with Prof Oubay Hassan, Dr Ruben Sevilla and Prof Kenneth Morgan, using reduced order modeling of Maxwell's equations to facilitate the design and optimisation of nano-scale structures for coatings on thermal solar panels. This work was undertaken in collaboration with industry partners LIST.

Most recently I was employed (here at Cardiff) on a research project investigating indoor transmission of COVID-19, with particular interest in the impact of air purification devices. The research was carried out alongside Dr Katerina Kaouri and Prof Ian Griffiths and in collaboration with industry partners Smart Separations Ltd.
