Research Interests:

Geochemistry/igneous petrology/geological oceanography/volcanology

My interests are focused on understanding the composition and structure of the Earth, with a focus on chemical exchange between the deep interior, the crust, and the atmosphere and oceans of Earth. I use both land and oceanographic field studies, combined with a variety of analytical and experimental tools to probe the composition of sediments and volcanic rocks to place constraints on mechanisms of plate tectonic processes and their impact on the evolution of the composition and structure of Earth on a variety of timescales.
