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