I am a third year PhD student on the Mathematics for Real-World Systems CDT at the University of Warwick, under the supervision of Dr Louise Dyson and Dr Michael Tildesley. I am interested in epidemiology, network science, applied dynamical systems and statistical physics.
I am currently researching potential indicators of disease elimination using the theory of critical slowing down. I focus on the application of early-warning signals to epidemiological time series data, using real-time analysis of statistical indicators to inform control policies for disease elimination. In particular, I have developed techniques for detrending time series data and addressed challenges of imperfect data, such as aggregated incidence data.

Work Experience and Study Groups
- IBM Research UK, Feb-April 2020
- 3 month internship in the Enabling Technologies Data Group, under the supervision of Dr Anne Jones. Project involved developing scalable tools for forecasting malaria in sub-Saharan Africa by integrating large datasets on climate drivers (utilising forecast products from the Weather Company, an IBM business) with simulation models. I learnt a variety of data science techniques for handling spatiotemporal data, including leveraging high-performance computing (HPC) and Big Data technology.
- AI in Health & Care Study Group, May 2019
- Problem solving week with academics from a variety of UK institutions. Problem presented by isardSAT, using machine learning techniques with earth observation data to predict precipitation and infer the risk of mosquito habitation. Funded by UKRI
- Mobile App Developer, Nov-Feb 2019
- Part-time app developer for the Green Research Group, University of Warwick. Role involved ensuring the functionality and providing technical support for users of an app which tracks and reduce lameness in sheep flocks.
