The steady expansion of global and regional seismic networks and the routine archival of seismic data at open-access data centers provide seismologists a wealth of high-quality, broadband ground motion data. Using new theoretical developments and the ever-increasing computing power of PC clusters, we can analyze seismic data in great detail and undertake seismological investigations of Earth's interior that were unimaginable less than a decade ago. Seismology continues to take a leading role in global geophysical research.
My research involves seismic tomography (a 3D imaging technique akin to medical CAT scanning) to construct large-scale models of seismic structure, and waveform modeling of body wave signals from regional arrays to refine tomographic models in well-imaged regions of the deep Earth. In collaboration with other geophysicists, I relate seismic models to structural heterogeneity and dynamic processes in Earth's interior.
