I am a Senior Lecturer in Geospatial Health at the UK Small Area Health Statistics Unit (SAHSU), part of the MRC Centre for Environment and Health.

My research focuses on two themes: 1) Geographical variations in population health, with particular focus on urban systems; and 2) environmental and health inequalities.

The priority of both research themes is to address the future challenges of environmental change and how adaptation and mitigation strategies can help to create fair and healthy places.

Both themes are supported by the development of advanced geospatial methods to harvest and improve emerging information sources and explore spatial patterns of disease.

Many of the studies I lead on, or contribute to have high potential public health impact, often with policy relevance. Communicating my scientific research to a wide audience both within academia and outside academia (e.g. via journalists, NGOs and outreach activities) is a vital part of my work.

As head of the Geospatial Health Group within the Department of Epidemiology and Biostatistics I am also working on the development and application of novel geographical approaches and methods for exposure assessment and environmental health analysis making use of advanced Geographic Information Systems (GIS) methods.
