I am a Professor of Atmospheric Physics and Head of Atmospheric, Oceanic and Planetary Physics in the Department of Physics and a Fellow of the new Reuben College.
I also lead the Climate Processes Group and serve on the steering group of the Oxford Climate Research Network.
My research addresses physical climate processes in the context of anthropogenic perturbations to the earth system as the underlying cause of climate change and air pollution. Focal points of my research are cloud and aerosol physics, their interactions and their role in the climate system.
