My research group studies the solid Earth and environment primarily using the tools of seismology. Our research relies on the pursuit of a broad understanding of interdisciplinary Earth systems, innovative use of time series data science methods and numerical modeling of wave propagation, and field projects to fill important data gaps. We often apply or adapt seismic imaging methods to resolve subsurface structures that give insights into the geologic history and contemporary state of tectonic and magmatic systems as well as the underlying deep Earth convective processes. Analyzing the properties of concentrated sources of seismic energy like earthquakes & explosions or diffuse sources of seismic waves like stream flow and ocean waves provides complementary insights into modern Earth systems and human activities.
