Research Interests

My research focuses on the geodynamical processes of the convecting mantle, lithosphere, and crust associated with magmatism and tectonics throughout the ocean basins. The research tools I use include geophysics (seismology, gravity, topography), geochemistry, and numerical models. Examples of my recent projects are illustrated and explained below.

•Mantle deformation and seismic anisotropy

•Dynamics of upper mantle flow and magma generation

Double-layering of the Hawaiian

mantle plume

Geochemical variations at intraplate hotspots caused by variable melting of

a veined mantle plume

Small-scale convection as a mechanism for intraplate volcanism

•Geophysical constraints in the structure of the crust and upper mantle (click images for information)

Dike complexes, cumulate cores, and extrusive growth of Hawaiian volcanoes

Landsides, submarine volcanism, and the origin of the South Kauai Swell

Gravity anomalies and the evolution of Kauai

 

•Mantle dynamics and geochemical variations at hotspots and mid-ocean ridges (click image for information)

•Faulting and magmatism at mid-ocean ridges (see movie of numerical simulation)
