My work is concerned with understanding the interactions between climate and chemistry in the stratosphere using a range of tools from theoretical frameworks to numerical models. I am based in the Mathematics department at the University of Cambridge.

I am currently collaborating with people in the Atmosphere, Ice and Climate group at BAS as part of a Marsden project (Led by Holly Winton) on how did changing sea ice conditions have impacted primary production in the Ross Sea over the past 200 years.

I have previously been a postdoctoral researcher at BAS working on the ISOL-ICE project (https://www.bas.ac.uk/project/isolex-isotopic-constraints-on-past-ozone-layer-and-stratosphere-troposphere-exchange-in-polar-ice/) which explored the use of a novel isotope proxy in polar ice to constrain past ozone layer changes over Antarctica.

Research interests

Chemical, dynamical and radiative interactions in the stratosphere. Stratosphere-troposphere coupling.

1. ISOL-ICE

   This project collected a shallow ice core from East Antarctic Plateau to reconstruct past ultraviolet radiation and therefore the ozone layer for the past 1,000 yr by measuring the isotopes of nitrogen and oxygen in the nitrate ion.
