I am a professor of physical climate science based in the Physics department at Oxford and at Pembroke college, where I have been since 2013. My work centres on the physics of atmospheric circulation and how this shapes weather and climate patterns around the world. Improved understanding of this physics is helping us to predict changes in the weather further ahead of time, and also to provide more detailed and trustworthy information on how climate patterns are changing. 

Particular current interests include the dynamics underlying polar weather patterns, circulation structures in the Southern Hemisphere under climate change and the link between emerging trends in the jet streams and tropical circulation. For a full list of publications, see here.

Much of my work has revolved around the mid-latitude jet streams; arguably the greatest weather systems on Earth. If you live anywhere in mid-latitudes, the jet stream is likely the most important factor affecting your weather and climate. If you want to find out more, please check out my book on the jet stream, written for a general audience.

At Pembroke I organise the Physics course and teach some of the maths and fluid dynamics options for Physics students. I sit on Governing Body and have a particular interest in helping the college to achieve its ambitious goal of decarbonising its estate.
