My research focuses on biogeochemical cycles of climatically important species in the atmosphere and ocean. I investigate the processes governing their distributions and budgets using numerical model simulations (global and regional) together with available measurements (land-based, aircraft, shipboard and satellite). My Ph.D thesis work, at Princeton University, focused on the processes governing marine nitrogen cycling and the ocean-to-atmosphere N2O flux. I then moved to the Atmospheric Chemistry Modelling group at Harvard to conduct research into aspects of the global carbon cycle, including (a) applying ‘top-down’ inverse analyses to quantify land and ocean carbon fluxes to the atmosphere, and (b) evaluating the potential value of measurements of other atmospheric trace species with similar sources and sinks (e.g., CO, COS) to constrain estimates of CO2 fluxes to the atmosphere.
I have recently completed an RCUK Fellowship at the University of East Anglia’s School of Environmental Sciences. My research here combines my atmospheric and oceanic interests, and focuses on (a) understanding how the processes governing the global cycles of carbon, nitrogen and sulphur may change under changing anthropogenic and environmental conditions, and (b) in evaluating the potential feedbacks on climate.
