- Seismic Attenuation

- Multidisciplinary Interpretation of Seismic Models

- Evolution of Oceanic Lithosphere

- Continental Cratons

- Seismic Noise

 

 

My research seeks to illuminate the thermal, chemical, and physical state of the Earth’s interior. Knowledge of these properties of the solid Earth is critical for understanding mantle convection, the motions of tectonic plates, and the thermal evolution of the planet over time. Specific scientific questions that motivate my research include:

 

  • What controls the depth of the ocean basins? How variable are mantle temperature and composition beneath ocean basins? How does oceanic lithosphere evolve over time?

  • What is the nature of the asthenosphere, and what properties differentiate it from the lithosphere?

  • How are continents assembled, and what factors have allowed them to remain stable over billions of years?

  • What is the distribution of partial melt in the mantle, and what is its connection to volcanism at the surface, for example in the Basin and Range province of the western U.S.?

 

To address these and other questions, I analyze the propagation of seismic waves – including their speed and rate of energy loss (attenuation) – generated by earthquakes. I also interpret seismic models together with data sets from other disciplines, such as geochemistry and mineral physics, in order to be able to quantify the range of temperatures, chemical compositions, and other parameters that characterize crustal and mantle rocks.
