I joined the British Antarctic Survey (BAS) in 2014, after 12 years at the University of Cambridge. I am an atmospheric modeller, using three-dimensional numerical chemistry models, including the UK Earth System Model (UKESM–UKCA) and the p-TOMCAT chemistry transport model, to investigate atmospheric processes. My research focuses on polar and global atmospheric chemistry and its interactions with climate. In particular, I investigate atmospheric oxidising capacity, including ozone, halogens and NOx, as well as polar aerosols and their impacts on climate through interactions with clouds.
My research has made two major contributions to our understanding of polar atmospheric chemistry. First, I developed a detailed tropospheric bromine chemistry scheme, demonstrated its critical role in driving tropospheric ozone depletion, and identified a new mechanism for the release of reactive bromine in polar regions. Second, I pioneered the concept of sea-salt aerosol production from windblown saline snow particles over sea ice and developed a parameterisation for this process, leading to the identification of a previously unrecognised source of sea-salt aerosol over the sea-ice zone.

Research interests

• Blowing snow and aerosol production: Microphysical processes controlling aerosol production from blowing snow and their implications for polar atmospheric composition and climate.
• Polar boundary-layer chemistry: Snow chemistry and snow–atmosphere exchange, with a particular focus on polar spring Bromine Explosion Events (BEEs) and associated Ozone Depletion Events (ODEs).
• Stratospheric halogens and ozone: The impacts of very short-lived bromocarbons, halogen interactions, and volcanic emissions on stratospheric ozone.
• Atmospheric mercury chemistry: Oxidation and atmospheric processing of elemental mercury, particularly in polar environments.
• Polar winter climate: Processes governing polar winter climate, with a particular focus on poorly understood aerosol, cloud, chemical, and surface–atmosphere interactions.

Collaborations

I welcome cross-disciplinary collaborations and have worked with outstanding scientists across a wide range of disciplines, encompassing atmospheric modelling, field observations, data analysis, and laboratory experiments. These collaborations have been an important source of scientific learning and have consistently led to new insights, innovative approaches, and fruitful research outcomes.
