Atmospheric Chemistry Research Group

I am a research associate in Professor John Pyle's group in the Centre for Atmospheric Science, and co-ordinator for the Cambridge Centre for Climate Science (CCfCS). For 18 months until November 2013 I was also a NERC policy placement fellow, advising Defra on air quality modelling


I use computer models (pTOMCAT, a global 3D chemical transport model; NAME, a Lagrangian particle dispersion model; and CiTTyCAT, a Lagrangian photochemical model) combined with field observations to study atmospheric composition, processing and transport.


Research Interests


  • The quantification of different processes acting on the composition of an air mass during its transport
  • Using measurements in combination with models to improve our understanding of atmospheric composition 
  • How to represent small-scale processes (e.g. chemistry) in a global model
  • How to represent mixing in a Lagrangian model
  • The quantification of the magnitude and variability of methane emissions in the Arctic
  • The role of nighttime chemistry in relation to daytime chemistry, and the roles of gas-phase and heterogeneous chemistry at night.

Projects I work on/have worked on:


  • MAMM: Methane and other greenhouse gases in the Arctic – Measurements, process studies and Modelling.
  • RONOCO: the Role Of Nighttime chemistry in controlling the Oxidising Capacity of the atmOsphere
  • AMMA: African Monsoon Multidisciplinary Analyses
  • ITCT-2k4: Intercontinental Transport and Chemical Transformation 2004.

I am also interested in science communication and am the knowledge exchange representative for the MAMM project. Follow our activities on the MAMM project blog: http://arcticmethane.wordpress.com. 


I enjoy getting involed in all kinds of science communication activities, from open days with hands on activities to shcools lectures to writing articles and blogs for a more general audience. Here is a selection of some of the activities I've worked on:


Arctic methane: What’s the story? (13 August 2013)


My flight logs: 1, 2, 3.


Tag – you’re it! Chasing atmospheric tracers (22 March 2013)


Stock market crash hits EGU General Assembly shocker! (2 May 2012)


Megacities at EGU2012 (26 April 2012)


  • Featured on the Kung Fu Science web site, including videos discussing and demonstrating the physics behind breaking boards. Also featured in a 4 minute piece with BBC 1 for The One Show, which was broadcast on 18 February 2009.  
  • Given schools lectures on air quality and climate change, and the physics of kung fu.

Find me on twitter @civiltalker, and sporadically on my personal blog and my Experiments of a culinary chemist blog.
