My research focuses on ambient noise tomography, and the extent to which crustal properties such as site-response, attenuation, and scattering can be resolved from signal amplitudes. Direct observations of the shallow crustal structure's effect on the ambient noise wavefield can be used to validate more traditional wave propagation methods for seismic hazard estimates.

My other studies include using ambient noise tomography with an OBS array offshore southern California, and the back projections of both earthquake rupture processes and tsunami waves.
