At the broadest level, I seek to understand the state, dynamics, and dominant processes of the solid Earth, as well as the interiors of other planets and satellites. Accurate seismic imaging is a crucial step toward this goal. On Earth, high-quality data from long-term broadband seismic installations and dense seismic arrays provide immense, information-rich datasets. On Mars, data from the InSight VBB seismometer has revealed tantalizing signals that are analyzed very closely in order to constrain the red planet’s crustal, mantle, and core structure. In both situations, accurate wave modeling techniques and sophisticated time-series analysis approaches — increasingly leveraging machine learning to identify trends and anomalies — provide crucial insights. At the same time, flexible approaches to inversion enable us to quantify uncertainty in a way that has not been possible before. What’s more, we now have the theoretical, computational, and observational capabilities necessary to constrain sub-surface structure simultaneously using multiple geophysical approaches, and to do so in a self-consistent fashion. This makes multi-geophysics investigations of near-surface structure on and off Earth particularly exciting for me. Therefore, my efforts primarily focus on:

1. Developing and applying new techniques for imaging sub-surface structures, including full waveform modeling and self-parameterizing inversions;
2. Describing and quantifying the relationship between deep processes and structures and surface tectonics on global and regional scales;
3. Leveraging sophisticated analysis approaches to identify trends, anomalies, and signals that can lead to key discoveries
