My current research interests centre on the relationship between the urban environment and population health inequities and the role of urban planning in mediating this relationship from an environmental justice perspective, with a focus on the global South in general and sub-Saharan Africa in particular. My interests stem from an understanding of urban health risks across a spectrum of hazards, ranging from everyday events (such as biological pathogens and road traffic accidents) and 'small' disasters (such as localised flooding and landslides) to large-scale disasters (such as storms and floods). Key interests include:

• The accumulation of environmental and health risks in cities and the implications for urban planning, with a particular interest in informal settlements
• The data and methods needed to understand and address the socio-spatial distribution of urban population health inequities and their determinants at the intra-urban scale (within urban centres) and inter-urban scale (between urban centres)
• The development of community-driven approaches to urban risk reduction in partnership with civil society and local government
• The development of an integrated urban planning and public health agenda tailored to the particularities of urban change in the global South
