Epidemiology and public health

The focus of this theme is ‘big data’ in relation to patient numbers and populations, for example electronic health records as opposed to complex biological data-sets about single patients.


Infrastructure and Environment to support this NIHR Theme

The Public Health Section at ScHARR has diverse and well-established collaborations with policy makers, commissioners, service providers and communities in the NHS, local government, third sector and organisations in Sheffield, the United Kingdom and globally.

As a section we produce high impact applied public health research and knowledge exchange; we are successful in getting research evidence into practice, for example, developing public health guidance for NICE and Public Health England (PHE). The section supports public health research capacity development, and is host to: the Sheffield component of the School for Public Health Research (SPHR); the NIHR Public Health Research Review Team; Wellcome Trust Doctoral Training Centre for Public Health Economics and Decision Science; Sheffield Alcohol Research Group; and Applied Research Collaboration (ARC). We also work in partnership with the flagship University Research Institutes: Healthy Lifespan Institute and the Institute for Sustainable Food in developing collaborative research programmes, both locally and globally.

In the field of infectious diseases, the University of Sheffield performs a wide range of epidemiological and vaccine studies, with the aim of improving community health in the UK and overseas. Applying the data and clinical material collected in these studies to our high-throughput immunological screening and next generation sequencing pipelines we employ population level analytical tools to understand immunity, pathogen transmission and vaccine impact. Our current research focuses on assessing the impact of vaccines on antimicrobial resistance at an individual and host/pathogen population level.

This team also forms part of the cross-faculty Florey Institute, and actively partners with STH and the CTRU at ScHARR. Relevant external collaborators include the Universities of Oxford, Cambridge, LSHTM (Zimbabwe and AMR groups), and Imperial and we actively contribute to external groups including the WHO (VPD surveillance, vaccines for AMR).
