Research

Research interests

3D Earth imaging:

  1. Seismic wave propagation and finite frequency effects in local and regional earthquake tomography.
  2. Joint inversion of Ambient Noise Tomography and Receiver function data to constrain lithospheric structure.
  3. Hierarchical and Trans-Dimensional Bayesian inference and its application to seismic imaging problems. 

Earthquakes and volcanos:

  1. Probabilistic Bayesian Inversion to constrain earthquake source complexity.
  2. Effect of 3D heterogeneity on Centroid Moment Tensor.
  3. Directivity and rupture propagation of shallow and deep large earthquakes.
  4. Complex earthquakes, caldera collapses and volcanic eruptions.

Seismicity and structural tectonics:

  1. Architecture of Megathrusts and the rupture processes of large earthquakes. 
  2. Earth structure and deep seismicity (>300 km).
