Recent Master’s graduate from the Niels Bohr Institute at the University of Copenhagen, Denmark. My thesis involved lab and field work with the Centre for Ice and Climate research group working in the Continuous Flow Analysis team developing a novel, portable instrument for in-situ melting and analysis of firn cores. I have been at BAS since November 2017 as part of the ISOL ICE project where I analyse snow, firn and ice core samples for nitrate to establish a more than 1000 year-old proxy record for UV and ozone in Dronning Maud Land in Antarctica.

Research interests

• Measurements of stable isotopes of nitrate, water and air from the ice core matrix
• Abrupt climate change events during the last glacial
• Ice core chronologies and past climates
• Analytical method development
• Measurements of sea ice extent by proxies
• Ice sheet flow modelling and evolution

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.
