I joined St John's in October 2012 as a Research Fellow in the Sciences and Mathematics. I am a Professor of Epidemiology at The Wellcome Trust Centre for Human Genetics. I am also Professor of Global Health at the University of Washington and Director of Geospatial Science at the Institute for Health Metrics and Evaluation (IHME).
I was elected to the Board of Trustees of the Royal Society of Tropical Medicine and Hygiene in 2012 and from 2013 to 2015 served as its President.
My work is funded by a Wellcome Trust Senior Research Fellowship which allows me to manage 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 European Union 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. Some of our most recent work of our group has been to map the zoonotic niche of Ebola.
