Structural Seismology and Tectonophysics
My primary research interests as a structural seismologist are in reconstructing the evolution of the dynamic Earth through the study of earthquakes, tectonic processes, and seismic imaging. Much of my work is focused on the three-dimensional structural evolution of the lithosphere and mantle near plate boundaries, such as beneath the western United States, Caribbean, Mediterranean and Indo-Australia, which are all seismically and volcanically active.
Current and recent research projects include:
Using dense seismic arrays to map deep mantle sharp features – funded by NSF Geophysics
Slab structure and dynamics of arcuate shaped subduction zones – NSF CAREER award
Transitions in the Banda Arc-Australia continental collision as a bridge to understanding mantle and lithospheric controls on surface tectonics – funded by NSF Tectonics/Geophysics/Global Venture Fund
Evolution the lithosphere and upper mantle in the westernmost Mediterranean through imaging portable broadband seismometers deployed in Spain and Morocco – funded as part of the NSF Continental Dynamics PICASSO project.
Mapping the Moho depths across faults in Southern California – funded by SCEC.
Evolution of the lithospheric and mantle structure of the Colorado Plateau and surrounding regions using USArray Transportable Array data – funded by the NSF Earthscope program.
Recent funding to establish earthquake monitoring in Timor Leste through Geoscientists Without Borders program.
December 2014 paper in Nature with Alan Levander and co-authors on subduction driven recycling of continental lithosphere.
