Research Area:
Interests include:
- Partial differential equations and their numerical methods
- Modelling PDE behaviour on evolving surfaces and evolving domains
- Computational methods for mathematics
- Mathematics with applications
- Physical models for mathbiology
My most recent research includes working with the
University of Sussex and local health care providers on the well-posedness of infection models for hospital admission rates.
Our current focus is on showing existence and uniqueness to a non-linear boundary value problem which is formed using the hospital data.

I have recently completed my PhD on the use of mathematical models to simulate ultra-high frequency wave propagation. Concentrating on modelling wifi propagation within a domestic indoor environment.
Currently looking at the method of geometric optics and adapting this to account for general domains. This will then be used to optimise antenna considerations using linear optimisation methods.

Previous research in the area of maths biology looked at modelling reaction diffusion problems on the surfaces of cells.
This used evolving surface numerical partial differential equation methods.

Education:
PhD at the University of Bath
Working with support from BT and the Smith Insitute I developed a new method for modelling the channel from WiFi propgation.
The main focus of this method was to store key information and to reduce the number of calculations being performed.
This information can then be used as inputs to optimisation methods which are not compatible
with the previous propagation models.
This project was align to the doctoral training centre SAMBa who currently have funded PhD positions available.
Mmath at the University of Sussex with an award for an outstanding Mmath project.
The University of Sussex inspired me to follow my passion for Mathematics.
I was fortunate enough to benefit from the university's Junior Research Associate scheme.
I recommend the scheme to any undergraduates looking to get an insight into a research career. The two placements I completed allowed me to investigate
a new area of mathematics without the distraction of assessment. In this time I developed a love for mathematics and in particular applied mathematical research.
