Introduction

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.

Research Projects

WM-Air

West Midlands Air Pollution Improvement

WM-Air is a five-year initiative to support the improvement of air quality, and associated health, environmental and economic benefits, in the West Midlands, applying existing air quality, health and economic science to deliver regional impact.

ASAP-Delhi

​

Air Pollutant Sources in the Delhi NCR

ASAP-Delhi will provide authoritative assessment of the sources, formation process, burden and characteristics of air pollutants in Delhi, with a philosophy of deriving pollutant source, budget and behaviour insights from direct atmospheric observations.

AIRPRO-Beijing

​

Air Pollution Sources and Processes in Beijing

The AIRPOLL and AIRPRO projects will identify the emission sources and chemical transformations giving rise to poor air quality - haze - in Beijing.

SNAABL

​

Sources of Nitrous Acid (HONO)

Nitrous acid (HONO) is emitted by vehicles alongside nitrogen dioxide, by soil bacteria, and potentially from aerosol particles - affecting atmospheric oxidation - but the magnitude of these sources if not well understood.

ICOZA

​

Integrated Chemistry of Ozone

Ozone is harmful to human health, vegetation and ecosystems.  We are developing new approaches to understand ozone formation in the UK and elsewhere

React-SCI

​

Reactions of Criegeee Intermediates

Criegee Intermediates (CIs) are newly discovered atmospheric oxidants with the potential to remove SO2 and NO2 more rapidly than previously thought.  We are studying the reactions of CIs using large simulation (smog) chambers.
