I am an NCAS Research Scientist working with Prof. Alex Archibald in the Centre for Atmospheric Science. I use numerical models of the atmosphere to improve our understanding of atmospheric composition. My research includes developing surface emission scenarios and assessing global budgets for gases with a role in climate forcing and ozone depletion, including methane, molecular hydrogen and biogenic halocarbons.  I have experience using various models, including UM-UKCA and the Met Office NAME particle dispersion model.

My current focus is on understanding atmospheric methane concentrations, and how information on the isotopic composition of methane can help us quantify its source and sink processes. I am also involved in projects investigating methane emissions from gas infrastructure in the North Sea and the chemical and climate impacts of a hydrogen economy.
