Research Focus:

I am primarily interested in the effects and origins of magmatism on Earth, both in the present and in the distant past. I work from both the planet-scale on themes such as the formation of Earth’s crust and lithospheric mantle and global elemental cycling, down to local-scale investigations of the magma plumbing systems of volcanoes.

Current Projects:

Exploring Icelandic volcanic history through tephrachrology of deep-sea sediments
Geochemistry and petrology of recent volcanism along the Reykjanes Peninsula
Geochemical provincialism of magmas on the East African Rift
Stable isotope geochemistry of the Earth’s mantle as viewed through hot spot lavas and mantle xenoliths
