Research Interests

Material characterization, laser ultrasonics鈥�

Professor Murray鈥檚 research has focused on the development of novel techniques for the characterization of materials, structures, and biological tissues in a non-invasive manner. He has developed laser-based ultrasonic approaches for the measurement of elastic and thermal properties of nanoscale materials and for the detection of subsurface defects in, for example, microelectronic components. His research also involves multimode imaging approaches utilizing both ultrasound and light to detect abnormalities, such as early stage tumors, buried deep within biological tissue. Additional research interests include elastic wave propagation, nanoparticle based sensors, and the development of laser-based techniques to interface with nanoscale mechanical devices.
