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.
I currently research and develop models for the vector-borne disease human African trypanosomiasis (HAT), more commonly known as sleeping sickness. I lead the newly funded Bill and Melinda Gates Foundation (BMGF) 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. An international, multidisciplinary group of mathematical modellers and economists will work together with other researchers and national programmes to assess local elimination strategies, provide cost-effectiveness analyses and deliver an elimination investment case.
I also work under the Neglected Tropical Disease (NTD) Modelling Consortium which is funded by BGMF. Using novel mathematical models fitted to human case data from various endemic foci, my aim on this project has been to assess the likelihood that the World Health Organization's 2020 goal of elimination as a public health problem will 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 surveillence and targeting high-risk groups in screening.
Some of the other diseases I have worked on are:
