Research interests

I am responsible for the suite of atmospheric chemistry instrumentation at BAS, including instruments operating in the Clean Air Sector Laboratory (CASLab) at Halley VI station. I am interested in the chemical composition of the atmosphere and using observations from Antarctica to investigate drivers of atmospheric change. I also work with the Halley Automation Team to ensure experiments are maintained during the winter when Halley station is unmanned.
