Research Interests

My research is driven by the underlying goal to advance our understanding of fundamental geodynamic processes, such as volcanism, mountain building, continental rifting, and craton formation. To this end, I employ a wide range of geological and geophysical tools emphasizing earthquake seismology, active tectonics, and the analysis of seismic data to investigate structure and to infer associated Earth processes. Past and current research projects have focused on a variety of different geographic locations including Hawaii, Costa Rica, Saudi Arabia, Africa, Greece, and Antarctica.
