I am an academic researcher working at the intersection of geography and global public health. My early work on HIV/AIDS was influenced by Foucault’s writing on governmentality. Focusing on questions of health, governance and risk, it outlined the productive and transformative power of public health discourse. The forms of risky subjectivity produced and reproduced in discourse, and interventions enacted as behaviour and space are reconfigured in the name of health, remain key areas of research interest. ​

Working in collaboration and across disciplinary divides is a strong feature of my approach. I have collaborated with geographers from around the UK and North America, which is reflected in my research and writing. More recently, I have established cross-disciplinary projects with colleagues in the Wolfson Institute of Preventive Medicine and the Blizard Institute at Queen Mary. The latter has extended my research interests in critical global health to include several projects exploring the intersection between migration, mobility, and undernutrition in Zimbabwe.

I joined Queen Mary University of London as a lecturer in 2007 and was made Professor of Global Health Geography in 2022. Prior to joining Queen Mary, I held a Research Fellowship with the influential health geography research cluster at the University of Portsmouth (1998-2003), then headed by Professors Kelvyn Jones and Graham Moon, before moving to Loughborough University. I am a Fellow of the Higher Education Academy and Fellow of the Royal Geographical Society.
