My research focuses on examining different aspects of the seismic source to learn more about the physics of earthquakes. I use earthquake catalogs to examine remote dynamic triggering of seismicity, as well as analyze waveform data to obtain source time functions of earthquakes, and model earthquake source parameters. My current research employs these techniques to study the seismic source from three perspectives, namely (1) the remote dynamic triggering of earthquakes from large, distant mainshocks, (2) the source parameter scaling of low frequency volcanic events, and (3) the radiated energy of earthquakes on faults of varying degrees of surface roughness.
