My research focuses on direct and inverse problems involving wave motion. Example topics include inverse scattering, waves in periodic and random media, geodynamics, and nonlinear waves in soft solids. We tackle the scientific and engineering challenges using analytical, computational, and experimental tools. Target applications of our work include nondestructive evaluation (NDE) of materials and structures, seismic imaging, medical diagnosis, and wave manipulation by architected materials.
High-frequency inverse scattering
This study [61] deciphers the Topological Sensitivity (TS) as a tool for 3D anomaly reconstruction in the high-frequency regime. The video shows the TS map in a mid-section of an ellipsoidal anomaly w/increasing source aperture.

Waveform tomography of a hard defect
In [36], we pursue 3D seismic waveform tomography using surface observations. The video shows the evolution of a trial anomaly during nonlinear minimization, whose color indicates the inclusion's modulus (G>Gb).
