Biography

I am a research fellow within the Institute for Climate and Atmospheric Science (ICAS). I currently work in the TOMCAT/SLIMCAT global modelling research group. I completed my PhD in atmospheric chemical modelling in October 2012 at the University of Leeds. My present research examines the complex interactions between climate and atmospheric composition using numerical models. In particular, I am interested in the impact of biogenic halogen species on tropospheric and stratospheric composition (e.g. ozone, methane).

Research Interests

  • Atmospheric composition and climate
  • Halogen chemistry and impacts
  • Global chemistry-climate modelling
  • Biosphere-climate interactions and future change
