I am Professor of Atmospheric Chemistry Modelling, with particular research interests in modelling global scale tropospheric ozone and its interactions with climate change.
I am an Associate member of ACCENT+ (Atmospheric Composition Change – The European Network of Excellence), a member of the Royal Society Working Group on ‘Ground-level ozone in the 21st century’, a lead author on the 2007 HTAP (Hemispheric Transport of Air Pollution) interim report, and a lead author on the ATTICA assessment of the impacts of transport on climate and ozone depletion. I have been a contributing author to several IPCC assessment reports, including Climate Change 2013: The Physical Science Basis.
