Research Interests

My interests lie within the field of seismology and have currently focused specifically on:
  • Techniques of rapid magnitude estimation,

  • and High resolution imaging of fault zone structure using,

    • fault zone trapped

    • and head waves.
All as part of my working towards a Phd at the University of Southern California under my advisor Yehuda Ben-Zion.
