Research Interests
Professor Miller's research focuses on the physics of anisotropic, inherently inhomogeneous media. These systematic studies of the anisotropic properties of the heart have led to fundamentally new insights. In 1998 the NIH Grant supporting this research was awarded MERIT status, which is designed to "provide long-term, stable support to investigators whose research competence and productivity are distinctly superior, and who are likely to continue to perform in an outstanding manner." This research has provided the basis for significantly improved diagnostic images of the hearts of patients and has been incorporated into commercially available echocardiographic imagers in widespread use throughout the world. Current investigations include studies of the physics underlying nonlinear ultrasonic propagation and the consequences on generalized dispersion relations of requirements of causality.
