Research Interests

Structure, deformation, rheology, and anisotropy of the lithosphere and mantle; receiver functions and array processing; seismic noise wavefield; seismic and volcanic hazards

Current Research

  • Crustal fault zones and magmatic systems
  • Automated processing and correlation of large seismic and geological data sets
  • Stress, strain, deformation, and reactivation of inherited fabric in the lithosphere
  • Deformation and strength partitioning in Himalaya/Tibet, Zagros, western U.S.
  • Anisotropic rheology
  • Scaling of elastic anisotropy from mineral grains to seismic wavelengths
  • Deep ductile fabric and shear zone imaging
  • Tectonic history from combining xenolith data and seismic observations
