My research mainly focuses on the petrology and geochemistry of volcanic rocks.   I have two principal research interests at present. The first uses short-lived radionuclide abundances to study degassing and crystallization processes in young lavas and tephras. Volcanoes presently under investigation include Kilauea, Mount St. Helens, Mount Erebus, Augustine, Merapi, Montserrat, as well as several others in intraplate, rift, and subduction-related settings. The second studies the petrology and geochemistry of Eocene lavas erupted in the Izu-Bonin-Mariana forearc to determine the causes of subduction initiation and the subsequent evolution of the subducting slab-mantle wedge system.

Research opportunities are available in my laboratory for Ph.D., M.S., and undergraduate students.  See my Research page for information about ongoing projects. In addition, feel free to send me an e-mail for further information.
