Atmospheric processing controls the current and future composition of our atmosphere, and affects human and environmental health, air quality and climate. My research group addresses three areas of atmospheric chemistry central to these impacts :

  • Measurement and interpretation of ozone production in the atmospheric boundary layer
  • Sources and sinks for atmospheric oxidants: Impacts upon urban air quality and tropospheric composition
  • Sources and transformations of air pollutants in urban environments 

Our work combines laboratory, large simulation chamber, field measurement and numerical modelling approaches; we currently have an emphasis upon developing new integrated approaches to assess chemical processing (a complement to the traditional focus upon species abundance).  Our research delivers fundamental understanding of the atmospheric chemical system, in an applied context: providing knowledge to underpin policy developments to reduce air pollution.

Research

Atmospheric processing affects the current and future composition of our atmosphere, and impacts upon human and environmental health, air quality and climate.  My research group addresses areas of atmospheric chemistry and clean air science, including

 

- Understanding the sources and transformations of air pollutants such as Particulate Matter and Nitrogen Dioxide in the urban atmosphere, ranging from the UK to developing megacities such as Delhi

- Quantifying the sources and sinks for atmospheric oxidants: Impacts upon urban air quality and tropospheric composition from new processes such as the formation of Criegee Intermediates, HONO and particulate-mediated renoxification

- Applying air pollution science to improve local and regional air quality policy measures, to ensure these can most effectively and efficiently improve human and environmental health

 

Work in the group combines atmospheric field measurements, simulation chamber and laboratory studies and numerical modelling approaches; we currently have an emphasis upon developing new integrated approaches to assess chemical processing (a complement to the traditional focus upon species abundance).​

 

While we are aiming to achieve fundamental understanding of the atmospheric chemical system, our work also takes place in an applied context: providing the knowledge to underpin policy development to alleviate air pollution.
