Research Associate
I am an NCAS Research Scientist working with Prof. Alex Archibald in the Centre for Atmospheric Science.
I use numerical models and observations to investigate physical and chemical processes in the atmosphere. I work with UKCA, the United Kingdom Chemistry and Aerosols community model, based on the Met Office Unified Model. I have past experience in addressing the effect of model horizontal resolution on a number of different dynamical and chemical processes. Currently, I'm working on better integration of models and observational data.
Key Research Interests
- Decadal changes in tropospheric ozone.
- Model evaluation and comparison with observations.
- Tropical deep convection and its impact on Troposphere/Stratosphere exchange.
- Lightning emissions and their impact on climate.
- Very short lived ozone depleting species (VSLS) and their impact on stratospheric ozone at the Tropical tropopause
- Impacts of emission changes and climate on regional atmospheric composition.
