Research Interests (primarily in Seismology)
  1. Numerical simulations of 3-D seismic wave propagation in heterogeneous medium based upon the spectral-element method (SEM).
  2. Moment-tensor and finite-fault inversions using 3-D Green's functions for regional and global earthquakes.
  3. Constructions of 3-D sensitivity kernels by adjoint methods.
  4. Tomographic inversions based upon 3D initial models and 3D sensitivity kernels for frequency-dependent measurements at both the global and regional scales (Adjoint Tomography).
  5. Adjoint tomography of ambient noise-correlation data.
  6. High-resolution seismic imaging of scattered waves based on adjoint method.
  7. Nonlinear inversion/optimization methods; model resolution analysis.
  8. Fast kernel computations of 1D reference models for traditional tomography inversions.
