Research Expertise


Anna Hansell is an environmental epidemiologist, with a special interest in health effects of air pollution including that produced by volcanoes and other non-anthropogenic sources. Her background is in respiratory hospital medicine and subsequently public health medicine. She completed a PhD in epidemiology in 2004 looking at the impact of environmental risk factors on respiratory disease mortality in the UK. She is currently leading several studies examining the long-term impacts of air pollution exposure on health. She was a member of a study in Montserrat in 2007 investigating the effect of volcanic air pollution on children’s respiratory health.
