Overview
I am currently a Research Associate at the School of Pharmacy with research interests in the feilds of disinfection, including water sanitisation and surface disinfection for healthcare and food industries. I work in partnership with numerous external companies to aid their product development, test products according to standardised protocols and to develop ad-hoc testing approaches that accurately reflect product usage.
Part of my research includes testing of novel antimicrobials and biocides against numerous bacterial targets including bacteria that have formed dry surface biofilms (DSB).
My PhD project aimed to reduce the burden of catheter-associated urinary tract infections through the development of novel antimicrobial silicone materials and development of an early-warning sensor. The project led me to become passionate about the prevention and reduction of healthcare-associated infections (HCAIs) and since then I have been involved in projects that aim to reduce transmission of HCAIs through development of antimicrobial surfaces.

Biography
I graduated from Cardiff University School of Biosciences in 2001 with a 2:1 in Biochemistry and Physiology. During my undergraduate degree I was fortunate to undertake my disseration project in the feild of arthritis research in the lab of Prof. Vic Duance. It was during this placement that I realised that I wanted to pursue a career in academic research and the following year I was fortunate to gain a 3 year research assistant post with Prof. John Harwood in Cardiff School of Biosciences, again in the arthritis research area.
In 2005 I joined the lab of Prof. Vic Duance as a research assistant before taking an extended career break to care for a growing faimily.
Between 2011 and 2017 I worked as a senior research technician at the School of Dentistry, Cardiff University, working on various projects associated with oral stem cells.
Between 2017 and 2021 I undertook my PhD in the School of Dentistry, Cardiff University, under the guidance of Prof. David Williams and in collaboration with Technovent Ltd. Working with Technovent Ltd, I successfully developed novel antimicrobial silicone materials to reduce catheter-associated urinary tract infections and I developed a novel antimicrobial silicone formulation that was capable of being 3D printed. It was during my PhD that I gained an in-depth knowledge in microbiological handling and testing methods.
I later joined the School of Pharmacy & Pharmaceutical Sciences as a research associate where I currently work under the guidance of Prof. Jean-Yves Maillard on various projects associated with disinfection research.
