Extreme Pollution Episodes - Climate, Health and Societal Impacts

Satellite view of widfires

Extreme pollution episodes occur worldwide as a result of multiple factors including high anthropogenic emissions and wildfire emissions. I am particularly interested in wildfires which have become a frequent occurrence in both developed and developing countries, as a result of a warming climate, uncontrolled agricultural practices or are intentionally lit by humans. We use high resolution regional model simulations to investigate spatio-temporal patterns of these events and to assess the associated population exposure and mortality burden as well as changes to the Earth’s climate.
