Dr Clare Heaviside

NERC Independent Research Fellow


Clare Heaviside is a senior research fellow in the ECI, with research interests covering climate change impacts - particularly on health, urban climate and the urban heat island, air pollution and heatwaves. Her research is often multi-disciplinary in nature, with application to the physical and environmental sciences as well as public health and policy.

She has published on a wide range of topics, from tropical meteorology and ocean and atmosphere heat transport, to the health impacts of the urban heat island effect, heatwaves and air pollution. Her work has been published in journals such as Nature Climate Change, Environment International, the Lancet Planetary Health, the Quarterly Journal of the Royal Meteorological Society, Atmospheric Chemistry and Physics, and Environmental Health Perspectives. She has contributed to publications such as the 2012 IPCC Special Report on Extreme Events, and the national Climate Change Risk Assessments for the UK.

After an Engineering degree, Clare studied for an MSc in Applied Meteorology at Reading University, followed by a PhD in Atmospheric and Oceanic Physics at Imperial College, London. Aside from academia, she has over a decade of work experience in the private and public sectors, most recently at the Health Protection Agency and Public Health England (Government Agencies) on climate and air pollution research. Before coming to Oxford, Clare was head of Climate Change at Public Health England, coordinating climate change research across the agency, advising the government on the health effects of climate change and providing scientific evidence to feed into national policy.

Current research

Clare’s current research looks at the impacts of climate and environmental change, particularly in terms of health and in cities. She is interested in the additional heat burden of the urban heat island, whereby cities are a few degrees warmer than the countryside – since urban effects are often not well represented in global climate simulations – and the potential impact of urban interventions. She also links environmental and demographic factors to carry out exposure and health impact assessments for temperatures and air pollutants such as ozone, particulate matter and nitrogen dioxide. Recently, she has worked on international studies of projections of temperature related mortality under climate change scenarios, as well as extreme event attribution studies in terms of heatwave mortality.


Clare lectures on Masters of Public Health courses at the University of Birmingham and at the London School of Hygiene and Tropical Medicine on Climate Change and Health.
