Biography

As an Ice Core Analytical Scientist,  I develop and use a continuous flow analysis (CFA) system for measuring chemicals present in ice cores which have been drilled in Antarctica and Greenland. This work is part of the Chemistry and Past Climate Programme. I use techniques such as spectrofluorometry, inductively coupled plasma mass spectrometry (ICPMS) and fast ion chromatography (FIC), to analyse the chemical constituents of polar ice cores and reveal information about the environmental conditions of the past.

I use new analytical methods to improve our understanding of ice core dating, weather patterns, climatic change and pollution events on sub-annual to multi-millennial timescales. Some of my current research focuses on warming records in and around the Antarctic Peninsula; and the development of analytical techniques for tracing organic markers of biomass burning.

Prior to joining BAS my academic work centred on trace gases in both urban and marine atmospheres, the development of analytical techniques for measuring atmospheric composition; and modelling of the oxidative capacity of the lower atmosphere.
