I use dynamic rupture models to study the source effects of large mangitude earthquakes. My focus
is on using global near-field seismic observations to constrain on-fault slip rates during seismic rupture.

At the same time, I am interested in what information can be extracted from these rare near-fault recordings, and how refined geophysical models can help us to prepare for damaging ground shaking in communities that surround active faults.
