Dr Sean Beevers is Reader in Atmospheric Modelling in the School of public Health, leads the Environmental Research Group's Air Pollution Modelling team, and is a member of the MRC Centre for Environment and Health.

I have over 15 years’ experience in modelling policies aimed at reducing the air pollution exposure of city populations, and have worked closely with London policy makers to implement major changes to the city, from the London Congestion Charging Zone to the recent London Ultra Low Emissions Zone.

I have been Co-I or PI on 18 research council funded projects since becoming an academic in 2009 and have over 80 journal publications on air pollution and health, air pollution policy and climate related topics.

Research Interests

My research interests include the development of advanced human exposure models to better understand the sources of air pollution exposure indoors, outdoors and whilst travelling. I have led the development of coupled regional and local scale air pollution models able to provide predictions at detailed spatial and temporal scales for cities, countries and even continents. I am studying the co-benefits of air pollution and climate policies, using modelled exposure estimates in epidemiological studies, and am leading research into vehicle detection using satellite imagery.
