My research focus is earthquake seismology. My current research projects include the study of seismic surface waves and their application to seismic tomography and seismic shear-velocity estimation. I have completed a study to map the group-velocity variations across central Asia and I am working now to combine surface-wave dispersion with gravity observations to improve our images of the geologic structure beneath sedimentary basins in northwest China (the Tarim and Junggar). I am also working on methods that use high-resolution surface-wave dispersion maps in applications to nuclear explosion monitoring. I have also modeled seismograms from moderate-size earthquakes (e.g. Pymantuning, Pennsylvania) to estimate faulting geometry and depth, and analyzed records from the 1999 Izmit, Turkey earthquake to estimate the spatio-temporal rupture history.
