My academic work is focused at the nexus of population health science, environmental epidemiology and health geography, including interests in:

  • People-environment interactions and health behaviours

  • Health benefits of nature contact in health promotion

  • Innovations in wearables, data capture via smartphone, wireless sensor networks and spatial analytics.


Research Interests

I study the relationships between the quality of the environment and our health. I am particularly interested in people-environment interactions, the influence of environments on human health behaviours and decision making, and the influence of the environment (good and bad) on human health outcomes.

My research is interdisciplinary, drawing on health geography and spatial analysis, population health science, environmental science and sustainability, and environmental epidemiology. I also love gadgets, particularly gadgets that people wear to track their behaviours and locations, and those that measure the quality and characteristics of the environment. Some people call this kind of work "measuring the exposome".

Presently, I focus my attention on three interrelated research areas: nature experience and human health; investigating human health-related behaviours through wearables and location tech; exposure assessment work for epidemiological research.
