At the broadest level, I seek to understand the state, dynamics, and dominant processes of the solid Earth, as well as those of other planets and satellites. Accurate seismic imaging is a crucial first step toward this goal. I believe that we stand at a threshold of a transformation in seismology, one enabled by the concomitant proliferation of high-quality array data and the development of accurate wave propagation techniques capable of capturing the effects of realistic Earth structure. For the first time, we have in place the theoretical, computational, and observational infrastructure necessary to constrain Earth structure simultaneously using multiple approaches, and to do so in a self-consistent fashion. My continuing efforts have therefore focused on: 1. Developing and implementing new techniques for imaging structures within the Earth’s mantle, including full waveform modeling; 2. Describing and quantifying the relationship between deep processes and structures and surface tectonics on global and regional scales.
