The early part of my career focused on the establishment of co-ordinated air quality monitoring networks, including the London Air Quality Network, which became the largest urban network in Europe. I have since utilised this foundation in measurement techniques and data handling to develop analysis methods to characterise sources, trends and behaviour in urban air pollution. The Environmental Research Group’s central role in providing technical support to the Mayor of London has allowed me to specialise in intervention studies, evaluating the impact of a wide range of technological or policy driven initiatives to improve air quality. This research has high profile outputs which have been used as evidence for future national and international schemes.
