My research investigates the interactions between human health and the physical, social, and built environments. In particular, I am interested in understanding why certain populations are more susceptible to diseases and ill health than others, and the assessment of differential health impacts experienced by disadvantaged populations. Most of my work focuses on the social and environmental determinants of health in the context of low- and middle-income countries. To address the complexity of these research areas, I utilise large spatial data sets and tools from GIS and quantitative methods.
