I am interested in interactions between the biosphere and climate, mediated via the chemical oxidation of biogenic volatile organic compouds (BVOCs). BVOCs affect the atmosphere's oxidising capacity and thus methane lifetime (with consequences for the Earth's radiative budget) and contribute to aerosol formation and growth. Aerosols scatter radiation and aid cloud formation thus cooling the atmosphere. These interactions have the potential to cause feedback loops which could oppose or exacerbate climate change. As well as climate model analysis, I am also doing research on the fundamental chemistry behind the formation of the smallest particles, focusing on the interactions of peroxy radicals from various BVOCS, and incorporating this into the global climate models UKCA and UKESM. I have been involved in the 6th Coupled Model Intercomparison Project (CMIP6) looking at biogeochemcial feedbacks which will contribute to the evidence base used by the IPCC.
