As a member of the Submarine Volcanism project team, my research is focused on geochemistry and mineralogy of submarine-erupted rocks from a variety of geologic settings, including mid-ocean ridges, seamounts and islands, and continental margins. I determine the composition of rocks, sediments, and minerals in order to interpret volcanic processes and eruption styles as well as post-eruptive alteration by hydrothermal circulation.
