How is oceanic lithosphere created and modified? Why is the oceanic asthenosphere weak? How is mantle flow recorded within the lithosphere and asthenosphere? What is the scale and vigor of convection beneath the plates?
What can seismic noise reveal about how the cryosphere and hydrosphere interact with the solid Earth? How does near-surface structure impact intensity of seismic shaking?
Development of novel methods for imaging Earth's interior, incorporating diverse geochemical, petrological, and rheological datasets.
