I currently work on the project Complex Urban Systems for Sustainability and Health (CUSSH) funded by the Wellcome Trust under its Our Planet Our Health initiative. The project is aiming to develop evidence to bring about transformative change in cities to address imperatives for population and planetary health.

I lead a health evaluation of the Irish Government's Warmth and Wellbeing scheme, which is providing home energy efficiency upgrades to people in parts of Dublin who are in energy poverty and are living with chronic respiratory conditions.

I also contribute to the Lancet Countdown which is tracking global progress on climate change and health.

I have previously worked on the following projects:

• Sustainable Healthy Urban Environments (SHUE)
• Sustainable and Healthy Diets in India (SAHDI)
• PURGE
• Development of the Health Impacts of Domestic Energy Efficiency Measures (HIDEEM) model 
• Evidence review and modelling to support guidance on excess winter deaths and illnesses by the National Institute for Health and Care Excellence (NICE)
• PUrE Intrawise
• LUCID
• DAPPLE
