Teaching Responsibilities 2020/21:

Term 2: MA4M1 Epidemiology by Example

Research Interests:

Themes: Mathematical Biology, Epidemiology

Techniques: ODEs, PDEs, stochastic models, branching processes, numerial simulation, Bayesian model fitting

I am a mathematical epidemiologist interested in population-level disease dynamics. I have a particular interest in vector-borne transmission and neglected tropical diseases. I am keen on developing new modelling approaches and theory as well as answering highly focused applied research questions which can aid in the control or elimination of diseases, particularly in low-income settings.

I currently research and develop models for the vector-borne disease human African trypanosomiasis (HAT), more commonly known as sleeping sickness. I lead a research project, HAT Modelling and Economic Predictions for Policy (HAT MEPP), which aims to inform strategic decision-making around strategies for the elimination of HAT, and is funded by the Bill and Melinda Gates Foundation (BMGF). Under this project an international, multidisciplinary group of mathematical modellers and economists work together with other researchers and national programmes to assess local elimination strategies, and provide cost-effectiveness analyses.

I formerly worked as part of the Neglected Tropical Disease (NTD) Modelling Consortium. Using novel mathematical models fitted to human case data from various endemic foci, my aim on the project was to assess the likelihood that the World Health Organization's goals of elimination as a public health problem by 2020 and elimination of transmission by 2030 would be met for this disease. I have also evaluated the relative effectiveness of complimentary strategies in addition to typical medical interventions such as vector control, improved passive screening and targeting high-risk groups in screening.

Some of the other diseases I have worked on are:

- Visceral leishmaniasis
- Avian malaria in the Hawaiian honeycreeper
