My area of expertise is in measuring and modelling the deposition, concentrations and trends of ground-level ozone, although I have worked in other areas including acid deposition and NH3 exchange. I also work with a Chemical Ionisation Mass Spectrometer (CIMS) to measure various different species and assist with instrumentation for field sites and campaigns.
From June 2018 to June 2021 I will also be working on greenhouse gas dynamics with the James Hutton Institute in Aberdeen for most of my time, although I'll still be at CEH Edinburgh regularly. So if you'd like to get in touch please look for me there.
I was employed as secretary to the UK Photochemical Oxidants Review Group (PORG) in 1995 to analyse and interpret UK ozone monitoring data, and to assist in the production of their report and organisation of meetings. I played a similar role with the National Expert Group on Transboundary Air Pollution (NEGTAP) from 1999 to 2002.
Currently I am working on the measurement and modelling of non-stomatal ozone deposition as well as the land/atmosphere exchange of species such as aerosols, NH3, SO2 and NOx.
Prior to starting work at CEH I was employed by Motorola (to assemble and test mobile phones) and Teleco Oilfield Services as an electronic technician.
