Our lab is interested in the nonlinear propagation of ultrasound and mechanical waves and their applications to medical imaging and therapy. Our research has been motivated by the observation that for intense sources the speed of wave propagation is no longer constant and that this complicates the mathematical framework but it also creates new opportunities. The goal of our work consists of three parts: to develop the physics and simulation tools that describes nonlinear wave propagation, to develop new diagnostic ultrasound imaging methods, to characterize shear shock wave propagation and its relationship to traumatic brain injury.
