Field and laboratory measurements of atmospheric trace species concentrations and fluxes. Urban air quality and the impact on health. 

My research group, in collaboration with many other colleagues, uses a combination of field measurements and modelling to investigate atmospheric composition, surface-atmosphere fluxes, and air pollution, and the impacts of these on the terrestrial environment and on human health. Current areas of research include:

• Ambient particulate matter (PM) and NO₂ measurement validation and inter-comparison, and the measurement and modelling of small-scale spatial and temporal variations in urban air pollution for estimating human exposure;
• Characterization of airborne PM to determine its sources and atmospheric chemical evolution;
• High-resolution modelling of atmospheric chemistry, with particular focus on ozone, particulate matter and reactive-N, to understand current and potential future impacts on atmospheric composition and on human health burdens;
• Measurement of the concentrations and surface fluxes of trace gases from terrestrial systems such as wetlands, forests and bioenergy crops;

My research interests span the measurement of atmospheric trace species and their terrestrial exchange, and measurement and modelling of air pollution chemistry and its impact on health and ecosystems.
