Research Interests

I am Atmospheric Composition Change Group leader in the Atmopsheric Chemistry and Effects Science Area (pre November 2017: Biosphere-Atmospheric Interactions) led by Dr Stefan Reis.  My research interests cover rural and urban air quality with a focus on ammonia and reactive nitrogen species, led scientifically by Prof Mark Sutton. I work with long term observations and experiments, and with low and high tech instrumentation. I am interested in measurements, modelling and process studies to quantify processes and impacts of the current atmospheric chemical climate. 

I help develop the atmospheric science measurement strategy at Auchencorth Moss (WMO-GAW Regional station, ICOS Ecosystem station  UK EMEP Supersite and atmosperhic observatory platform). 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.

Project Manager of the Defra/EA UK Eutrophying and Acidifying Atmospheric Pollutants (UKEAP) contract operating the UK's rural monitoring networks and the UK EMEP Supersites.

I am CEH Project lead on the following: 

NERC SPF OSCA (2019-2022)

NERC SPF Clean Air QUANT) (2019-2022)

H2020 ACTRIS_PPP   (2016-2019)

I am contributing to many other CEH and external projects including currently the following projects and activities: 

On-going research interests include:

  • Development and maintenance of screening tools for assessing impacts of trace gas point sources
  • Development & deployment of instrumentation and samplers for measurement of trace gases and aerosols.
  • Volcano plume impacts in the UK: surface measurements and response planning
  • Transfer of knowledge and expertise in low cost, quality assured enviromental measurements
