Areas of research: 

  • Air pollution 
  • Behaviour change and digital technology
  • Sustainable cities 

Rosie's research tries to understand how we can use behaviour change and public engagement as a way to build cities that are healthier, fairer, more inclusive and more sustainable places to live. 

Take the example of urban air pollution. In the UK, air pollution causes 40,000 premature deaths a year and costs the NHS around £20 billion - one fifth of its annual budget. Typical solutions tend to focus on developing technology; electric vehicles, catalytic converters, clean fuels, filtration devices and better drugs. Yet encouraging people to drive less and walk and cycle more can reduce urban air pollution whilst reducing GHG emissions and improving public health through the increase in physical activity.

So why aren't we focusing on behavioural solutions to air pollution?

Because understanding why people behave in the way they do is not straightforward. This makes designing effective interventions to change peoples' behaviour difficult.

But not impossible.. 

Rapid advances in smartphone technology is making it easier, cheaper and quicker to communicate with people is ways that are personal and targeted, 'at-the-right-time' and at scale. Smartphones offer a huge opportunity to encourage entire populations to engage in healthy and sustainable behaviours, for their own health, the health of their community and the health of our planet. 

My research sits at the nexus of behavioural science, human computer interaction and environmental policy and asks how we can effectively use digital communication technology to stimulate a change in the public's behaviour in relation to air pollution.
