My primary research interest is in urban air quality and the identification of primary emission sources of gas phase air pollutants (such as Volatile organic compounds - VOCs) in urban areas, with the aim of understanding how and where these pollutants are emitted from and how this relates to estimates from national and regional emission inventories. Expert in the direct determination of VOC emissions using real-time chemical ionisation mass spectrometry (PTR-MS, SIFT-MS, CIMS) coupled with meteorological measurements through eddy covariance. Previous studies have involved deployment on both at ground sites and airborne platforms
