Research Area:
Interests include:
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.
Prof. Anotida Madzvamuse
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.
Prof. Chris Budd OBE, Dr Robert Watson, Dr Keith Briggs, Dr Michael Fitch
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.
Prof. Anotida Madzvamuse , Dr. Chandrasekhar Venkataraman

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.

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.

Today I ended up having a lengthy conversation with people in the gym who had no idea it's not just lecturers on strike and they wouldn't get paid. They were pretty supportive when I explained what we are fighting for. Keep the conversations happening and show support.

Had some great chats with students on the picket line this morning. Some standing in the rain just to learn more. Thanks for the support and don't be scared to stop for a chat. #UCUstrike #ucustudentsupport #ucureturnofthepicketline

Industrial visits always shock me by the low numbers of women to men. So day 1 I'm shouting out to my mum. Showing me maths was cool before I knew what maths was.
Finished her degree whilst bringing up tiny humans and she's an expert in her field. #womeninstem day 1 #stemwomen

It was fantastic discussing ideas with the wave modeling group at @UniofNottingham yesterday. Jotting down the overflow from my brain on my journey back to Bath. @SAMBa_CDT

On my way to @UniofNottingham with my @SAMBa_CDT cup. Giving a seminar on my work, only a tiny bit terrified.
