Professor Paul Elliott, CBE, FMedSci, FRCP, FPH trained in clinical medicine and epidemiology as a Wellcome Trust Clinical Fellow at St Mary's Hospital London and the London School of Hygiene & Tropical Medicine. He studied for his PhD in Epidemiology on the INTERSALT Study under the mentorship of Professor Geoffrey Rose. He remained at the London School working as a lecturer, and subsequently as senior lecturer and reader in epidemiology before being appointed as Head of the Environmental Epidemiology Unit at LSHTM 1990. In 1995 he was appointed to the Chair in Epidemiology and Public Health Medicine at Imperial College London. Since then he has managed the transformation of the Department of Public Health into the present Department of Epidemiology and Biostatistics in the School of Public Health. The Department has expanded significantly during recent years to encompass a wide-ranging programme of health research and extensive collaborations with national and international research groups, hosting both honorary and visiting staff. Paul Elliott is also Director of the MRC Centre for Environment and Health, which was launched in 2009 (as the MRC-PHE Centre for Environment and Health in  collaboration with King's College London) and forms a major part of the Department. The UK Small Area Health Statistics Unit (SAHSU) is also based in the department. Paul Elliott is an honorary consultant in public health medicine in the Directorate of Primary Care and Public Health of the Imperial College Healthcare NHS Trust. His contribution to public health research, most recently in response to the COVID-19 pandemic as director of the REACT community surveillance study was recognised with the award of a CBE in the 2021 Queen's Birthday Honours List.

Key Research projects:

  • The MRC Centre for Environment and Health was created in 2009 as the MRC-PHE Centre for Environment and Health. In 2019 the Medical Research Council became the sole sponsor of the Centre, which is now an established a centre for excellence in research and postgraduate training in the field of environment and health. Research themes include Environmental Exposures; Healthy Cities, Healthy People; Molecular Signatures & Disease Pathways. The Centre hosts postgraduate students and fellows funded by its PhD studentship and early career fellowship schemes. 
    MRC Centre for Environment and Health
  • The Small Area Health Statistics Unit (SAHSU) undertakes substantive epidemiological enquiries of environmental health problems and methodological research. SAHSU studies involve environmental modelling and monitoring as well as analysis of biomarkers (of exposure, effects and genetic susceptibility) in addition to the analysis of routine health statistics, to aid interpretation of causal inference. Small Area Health Statistics Unit (SAHSU)
  • AIRWAVE health monitoring study - occupational cohort study of long-term health in relation to the use of the TETRA communication system by police force personnel. Funding: Home Office, 2003-2018; MRC/ESRC, 2018-2023. The baseline survey took place between 2004-2015, with extensive data collection by a computerised questionnaire, a range of physical measurements, and collection of a non-fasting blood sample. A programme of follow-up health-screens to participants in Scotland and Wales is currently being resumed with funding support from the ESRC and MRC. Airwave is part of the national DPUK initiative and researchers interested in accessing the data can apply via the DPUK data portal.

  • UK COSMOS - International cohort study of mobile phones and health with data on >100,000 UK mobile phone users, part of a major long-term cohort study with approx. 300,000 participants from across Europe recruited in Denmark, France, Finland, The Netherlands, Finland and Sweden. Baseline data collection was in 2010-2012. In 2017 the first phase of follow-up was carried out with collection of data on participant health, mobile phone use and lifestyle. Data analysis and international collaboration is ongoing. 
  •  SCAMP Study - cohort study which is following several thousand secondary school pupils in 39 schools across London from year 7 through to year 9. The aim of this study is to investigate whether children’s use of mobile phones and/or other technologies that use radio waves e.g. portable landline phones and wireless internet, affects their cognitive and behavioural development. The first round of follow-up data collection ended in July 2018. SCAMP Wave 2 was recently funded by the MRC.

  • The REal-time Assessment of Community Transmission (REACT) research programme is a series of studies that seek to improve understanding of how the COVID-19 pandemic is progressing across England. To do this the progamme launched two studies in May 2020; REACT-1 and REACT-2. REACT-1 is a community survey of SARS-CoV-2 prevalence in England, based on repeated non-overlapping cross-sectional surveys of random samples of the population. At each round, self-administered throat and nose swabs and questionnaire data are collected from between 120,000 and 180,000 people ages 5 years and above, over a period of ~17 days, at approximately monthly intervals. The aim is to examine how widely the virus has spread and to identify any trends in prevalence. The REACT-1 data collection finished in March 2022 following 19 rounds of survey.
    REACT-2 assessed several different antibody tests to see how accurate they are and how easily people can use them at home. 
    Funded by Department of Health and Social Security.  A Collaboration with the Imperial Healthcare NHS Trust and IPSOS MORI. REACT2 includes a sub-study of a sample of keyworkers recruited from the Airwave police cohort study and fire service personnel.

  • REACT is a contributing cohort to the NIHR/UKRI CO-CONNECT project

    REACT-GE (Multi-omics to identify biological pathways underlying severity of SARS-CoV-2 infection) is a partnership between Imperial College, Genomics England and the GenOMICC Consortium. This study aims to address gaps in our understanding of SARS-CoV-2 virus, in particular with respect to differences in disease susceptibility, severity of infection and disease mechanisms. A multi-omics approach - encompassing whole genome sequencing, proteomic, transcriptomic and metabolomic analyses - will be applied to a sample of c.8000 mild/asymptomatic cases, to identify biological pathways that are protective of or deleterious to the response to SARS-CoV-2 infection.
  • REACT-LC (Long COVID) is a study funded by the UKRI, NIHR and DHSC as part of the Research into the Longer Term Effects of COVID-19 in Non-hospitalised Individuals programme. This study involves people in the community who have taken part in the REACT study and investigate why some people with COVID-19 experience symptoms for several weeks or months (Long COVID), while others have a short illness or no symptoms. REACT-LC is a collaboration with Genomics England.
