Climate change, environment, and psychology (CEP), Behaviour-change and CEP, Environmental and climate activism, Methodologies to strengthen CEP. My research focuses on psychology, environment and health in the global South. I have worked on studies of air pollution, urban housing, lead poisoning, mercury, as well as water and sanitation. I contribute to this field in the following ways: to identify the association between toxic environments and child development, to deepen and critique the concept of ‘behaviour’ in environmental health, to understand the role of activism in environmental health promotion, and to develop the research methodologies we use to study environment and health. Key projects include the behaviour and household air pollution project; the household, environment and development (HEAD) study and the politics of environmental health project.
