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 monitoring of hydraulic fracturing.
Seismic waves across an advancing fracture
Waves & Imaging Lab at the University of Minnesota: 20kHz ultrasonic waves propagating across an advancing fracture in a granite slab subjected to 3-point bending: in-plane (uy) displacement waveforms captured by SLDV.
