I am a PhD student based at BAS as part of the tropospheric chemistry group, and in the Earth Sciences department at Royal Holloway, University of London.

Current research: Methane is a potent GHG that has contributed approximately 20% to the Earth’s warming since pre-industrial times. The oceanic component of the global atmospheric methane budget is highly uncertain, it is necessary that we better understand how much methane oceans emit to the atmosphere in order to reduce the global methane atmospheric burden. As a result of climate change, high latitude marine environments are changing in ways that are likely to impact methane release to the atmosphere, highlighting the urgency of increasing understanding of methane from polar marine areas. I study methane in polar oceans using gas chromatography and in the atmosphere above polar oceans with instruments like Picarro and Los Gatos analysers. I also investigate sea-air methane fluxes through eddy-covariance measurements and bulk flux calculations to better understand the role of polar oceans in the global methane cycle.
