Professional summary

I am an Atmospheric Chemist interested in the use of atmospheric measurements to understand the composition and land-atmosphere exchange of gases and aerosols above various ecosystems, including urban megacities and peatland background sites. My work has focused on the use of high-resolution mass spectrometers, eddy covariance systems and multivariate modelling to give detailed chemical analyses of atmospheric species, and to characterise their source contributions. I am currently working on the development of the Aerosol, Clouds and Trace Gases Research Infrastructure (ACTRIS) network for the UK.
