The motivation for my research is to understand how the interior of a planet affects and controls the composition of its surface, and how volcanic degassing relates to long-term habitability.

In short, I want to understand the pathways followed by volatile elements subducted into Earth’s mantle over geological timescales, with a strong emphasis on constraining the origin(s) of diamond-forming carbon in the mantle, and the nature of the tectonic volatile cycle(s).

I also work towards understanding the formation and deep-time evolution of extra-terrestrial planetary atmospheres, such as those around Venus and Mars.
