My research program contributes to our understanding of the Earth's structure and composition as well as how the Earth deforms. My approach employs primarily seismic and geodetic tools to study first-order problems of geophysics and geodynamics that are of interest to a broad audience. A long-term focus of my research is to investigate processes related to subduction, a fundamental feature of the plate tectonic engine that drives the evolution of the Earth. However, the complexity of subduction zones is formidable and subducted lithosphere cannot be accessed directly at the Earth's surface, which make subduction zones arguably the most poorly understood part of the global tectonic framework. By constructing innovative experiments with high-resolution techniques, I seek to place new and important constraints on unresolved problems like convection, seismogenesis, and lithospheric evolution.
Possible thesis/dissertation topics:
- Seismic and petrologic structure of subducted lithosphere near Fiji and Vanuatu.
- Relationships between earthquakes, stress patterns, and mantle dynamics beneath South America and the western Pacific.
- Combined GPS and seismic estimates of convergent deformation in southern Mexico.
Current/recent graduate student research:
- Seismic and Aseismic Deformation of the Oaxaca Segment in the Mexican Subduction Zone.
- Segmentation of Non-Volcanic Tremor in the Cascadia Subduction Zone.
- Seismic Anisotropy and Thermo-Petrologic Evolution of Deep Subduction
