Biography

My research primarily focuses on using elemental and isotopic data on volcanic rocks and minerals to understand: (a) details of melt generation in different tectonic environments, (b) details of magma transport/storage/modification in the crust.

Research areas have included continental flood basalts (Paraná-Etendeka, East Greenland), subduction zones (Izu-Bonin-Marianas, Vanuatu, Lau Basin), and ocean islands (Iceland, Cape Verde). Recent work has focused on the off-axis alkaline magmatism of western Iceland, the post-spreading magmatism and rifted margin of the South China Sea, the magmatic plumbing system of Mt Taranaki (New Zealand), and the Precambrian basement rocks of Iowa.

I am also interested in applications of geochemistry to addressing research problems in a broader range of subjects, such as impact cratering, sedimentary geochemistry, geoarchaeology, and environmental lead pollution. I use various analytical techniques available in the department and in the MATFab facility:

  • (LA)-ICP-MS
  • SEM
  • EPMA
  • pXRF
  • XRF
  • Petrographic microscope
