Research Interests

I investigate spatial and temporal aspects of malaria disease epidemiology to provide an improved evidence base for more rational implementation of disease control. Time-series analysis, population dynamic theory, remote sensing, geographical information systems and spatial analyses are all exploited for disease risk mapping and disease burden estimation. In addition, I use these techniques to explore the range of factors that are likely to impact on malaria burden, as a result of global environmental change (particularly population growth, urbanization and climate change). This will enable the ever-changing baseline malaria burden to be estimated, against which intervention strategies can be more reliably evaluated.

My work is funded by a Wellcome Trust Senior Research Fellowship that allows me to manage the Malaria Atlas Project (, an international collaboration of researchers aiming to improve the cartography of malaria. My most recent research is focused at defining accurately human populations at risk of malaria and its burden at global, regional and national scales. I also now lead the mapping component of a similar EU funded initiative to do the same for dengue. I am increasingly interested in using internet resources to harvest data for mapping a broad suite of pathogens of public health significance. Updates are tweeted @simonihay.
