Tong Bai CV

Advisor: Ilya Tsvankin

Tong’s research focuses on Q-related processing in anisotropic media. With two developed viscoelastic VTI propagators based on GSLS model (for inversion) and Kjartansson’s constant-Q model (for imaging), he has conducted FWI for attenuation estimation, and demonstrated the necessity of understanding Q-anisotropy by applying Q-compensated time-reversal imaging for microseismic source characterization.

Advisor: Ilya Tsvankin

Vladimir’s research is focused on image-guided migration-based travel time tomography and waveform inversion for acoustic TI media.

Daniel Rocha CV

Advisor: Paul Sava

In order to obtain an improved estimation of the subsurface physical properties within fewer iterations, Daniel utilizes imaging operators derived from the wavefield energy norm for least-squares migration and tomography. Such operators exploit polarization and directionality from the extrapolated wavefields to mitigate artifacts that retard convergence towards the desired subsurface model.
