I graduated with a BSc (Hons) in Mathematical Sciences from University College Cork (Ireland) in 2016. This included a year abroad which I spent at the University of California, Santa Barbara. Throughout my degree I was consistently attracted by the potential of the applications of mathematics. Due to the multidisciplinary nature of the US education system, I was inspired to explore the possibility of using my skills to solve problems in other fields, in particular using the computer. This led me to the Tyndall National Institute where I worked as a research intern, writing code to simulate semiconductor lasers. My interest in the applications of mathematics and my desire to undertake a project which can really benefit society is what drew me to medical imaging. With this PhD, I have the opportunity to apply my skills in mathematical modelling and computer programming to develop state of the art technology with a huge potential for clinical impact."
