Biography
I am leader of the Atmospheric Composition Change group in the Atmospheric Chemistry and Effects Science Area of UKCEH.
My research interests cover remote, rural and urban air pollution with a focus on ammonia, particulate matter (PM) and other reactive nitrogen species. I am involved in the UNECE Task Force for Measurement and Modelling and the CEN WG11 on developing a European standard for ambient ammonia passive samplers and CEN WG42 air quality sensors.
