The effect of a low density residuum on geoid anomalies and topography
… correspondence between surface topography, seismic wave speed, and the geoid (gravitational potential). High seismic wave speed indicates cold material sinking, which pulls the surface downward. Thus, topographic lows are expected to correlate with seismic wave speed highs, contrary to the …

Inferring the thermomechanical state of the lithosphere using geophysical and geochemical observables
… 1, I correlate lower crustal rheology with seismic wave speed. Compositional variation is required to explain half of the total variability in predicted lower crustal stress, implying that constraining regional lithology is important for lower crustal geodynamics. In Chapter 2, I utilize …

Melt generation in the Earth's mantle at Convergent Plate Margins
… responsible for the large negative gradient in seismic wave speed observed at the lithosphere-asthenosphere boundary below eastern North America. These studies together advance our knowledge of how the recycling of tectonics plates on Earth affects melt generation in the Earth's mantle and …
