Biography
My research focuses on understanding the global biogeochemical cycles of carbon dioxide, methane, and other trace gases associated with climate change and ocean acidification. I am interested in improving estimates of the oceanic and terrestrial fluxes of these trace gases to the atmosphere on regional to global scales and exploring the physical causes of their spatial and temporal variability. My work includes atmospheric modelling, oceanic modelling, analysis of isotopic data, and statistical analysis of atmospheric and oceanic observations.

Scientists discover abrupt increase in CO2 uptake by the land biosphere
News article
12 July 2012
Scientists have discovered an abrupt increase in the uptake of atmospheric carbon dioxide by the land biosphere since1988. Without this natural increase in uptake, the amount of carbon dioxide in the atmosphere would probably have increased even more rapidly over the last two decades.
