I am a member of the Applied and Computational Mathematics Research Group and work on the project “Mathematical modelling and smart coatings: fighting the COVID-19 pandemic” with Dr Katerina Kaouri (PI), Prof. Ian Griffiths (University of Oxford) and Smart Separations Ltd (SSL). The project is funded by the Welsh Government (Sêr Cymru “Tackling COVID-19” call).

Working as a team, we are developing comprehensive mathematical models of the transmission of COVID-19 in indoor spaces, focusing on airborne transmission. Our novel modelling framework involves numerical and analytical solutions of advection–diffusion equations and Computational Fluid Dynamics simulations to accurately model air flows and transport of SARS-CoV-2. In this way we can investigate the effects of air-conditioning, ventilation and masks. We are focusing on classrooms and healthcare locations.

Furthermore, our models will be used to quantify the reduction in viral transmission when antiviral coatings are applied to locations with a high risk of transmission. A novel antiviral nano-coating technology has been developed by SSL and it has been shown to destroy a broad range of microorganisms: bacteria, fungi and 99.9% of viruses, including SARS-CoV-2. The antiviral coating can be applied to most surfaces such as masks and gloves and air filters in AC units, portable air sanitisers and respirators.

Currently, three PDRAs are employed on the project: Raquel Gonzalez , Xander Ramage and me.
