Fields of Study:

Igneous geochemistry
Mantle chemical structure and evolution
Uranium series isotopes Igneous geochemistry
Volcanology and volcanic hazards

Research Interests:

I am interested in both the long-term chemical evolution of the Earth's mantle, and mantle magma production and transport on shorter time scales. To examine these problems, I use major element chemistry, trace element chemistry, and variations in long- and short-lived radiogenic isotopes to study the means by which melts form in the planet's interior, how those melts are transported, and why they vary from place to place on the Earth's surface. In particular I study the chemistry and isotopes of volcanic materials erupted at slow-spreading mid-ocean ridges, where new crust is being formed. The processes by which lavas reach the mid-ocean ridges are complex, requiring imperfect mixing of magmas from different depths and a combination of quilibrium and disequilibrium processes during magma transport.
