We are seeking an excellent postdoctoral researcher to work on the epidemiology of poliovirus transmission, including statistical, GIS and model-based analysis of global surveillance data maintained by the WHO. This post is funded by the Bill and Melinda Gates Foundation and focuses on the epidemiology of wild-type and vaccine-derived polioviruses and the impact of different surveillance and vaccination activities. This work will provide the evidence base for strategic decisions by the Global Polio Eradication Initiative (GPEI) and involves close liaison with WHO, Gates Foundation, and our research partners in low- and middle-income countries. You will work in the VERG led by Prof Grassly and have access to excellent peer support from with other members of the Department of Infectious Disease Epidemiology and the MRC Centre for Global Infectious Disease Analysis. The post would be especially suited to someone with experience in epidemiological analysis or mathematical modelling of infectious disease data but we will also consider applications from enthusiastic individuals with appropriate mathematical, statistical or biological skills. You will be expected to produce high quality research, submit publications to scientific journals, attend and present at conferences and attend meetings with researchers and policy-makers relevant to the field. You will be based in the Department of Infectious Disease Epidemiology located at the St Mary’s campus of Imperial College London, Paddington.
