Areas of Specialization and/or Research Interests

My research is focused on investigating the physics of earthquake rupture and processes that trigger earthquakes and govern the development of seismic swarms, particularly in volcanic areas.

Techniques I commonly use include:
1) High-precision earthquake location
2) Earthquake source modeling (to understand the physics of earthquake rupture)
3) Seismic tomography (to image a volcano's interior)
4) Stress inversion studies (to understand the stresses driving earthquake failure).
