My research focus is concerned with global and regional climate change on scales of 100 years in the past, to 100 years in the future. Specifically, I research how climate change alters the atmospheric circulation, extreme events, and impacts on human health. I look at attribution of past climate trends and extreme events, and projected changes under future greenhouse gas emission scenarios. My particular focus at the moment is on how low emission scenarios, consistent with the aims of the Paris Agreement on climate change, may impact society through changes in health (heat waves, cold snaps).

Focused research topics include:

1. Stratospheric dynamics (mainly the polar vortex)
2. Mid-latitude dynamics and the relationship to extreme weather.
3. Temperature related health issues.
4. Attribution of past climate, and projections of future climate.
5. Extreme value statistics.
6. Planetary atmospheres in the solar system.
