Geophysics Seminar Schedule (2020-2021), (2019-2020)
Joubin-James Lectures and short courses (2018-2019)
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.
- Tomographic inversions based upon 3D initial models and 3D sensitivity kernels for frequency-dependent measurements at both the global and regional scales (i.e., adjoint tomography or full-waveform inversion).
- Adjoint tomography of multi-component ambient noise-correlation data.
- High-resolution seismic imaging of scattered waves based on adjoint method.
- Nonlinear inversion/optimization methods; model resolution analysis.
- Whole-mantle tomography based on kernel databases computed for 1D reference models.
- Microseismics and induced seismicity: event detection, source localization, mechanism inversions.
