I am a Professor of Atmospheric Physics and Head of Atmospheric, Oceanic and Planetary Physics in the Department of Physics.

I also head 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 aerosol and cloud physics, their interactions and their role in the climate system.

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 aerosol and cloud physics, their interactions and their role in the climate system. Aerosols are small liquid or solid particles suspended in air of both anthropogenic and natural origin. Cloud droplets form on aerosol particles so man-made changes in aerosol (precursor) emissions also affect the physics of clouds.

I am currently focusing my research on the highly uncertain interactions between aerosols and convective clouds, made possible through a grant by the European Research Council.
