My research focuses on the impact of present and future climate change on physical and biogeochemical processes in the ocean.  My work combines numerical models and 'real world' observations to better understand the drivers of changes in ocean properties.  I have a particular interest in the ocean's oxygen and carbon inventories and how they have changed over the recent past, with major implications for marine ecosystems.

I am also involved in research which uses climate models to better understand the impacts of climate change on population health via changes in heat injury risk.
