We combine field and laboratory work to understand the origin and evolution of Earth's crust, mantle and core and the chemical differentiation within and among each of those reservoirs. We also study the evolution of other planetary bodies such as Earth's moon and Mars.  Ongoing projects include the evolution of volcanic systems in subduction zone environments and hot spots, the chemical connections between the mantle and the volcanic arc in subduction zones, mantle mineralogy, the dynamics of core-mantle interaction, the volatile history of Earth's moon, the formation of mineral deposits associated with volcanic systems, and the evolution of the Martian mantle.
