  • Summary Statement of Research Interests

    My research is collaborative and has consisted of multiple disciplines. I have successfully completed projects at NASA/JPL, and USC. These projects were funded from NIH/NIHL, NASA/JPL, NSF, Caltech, USC, and other organizations. I was a research assistant and then a project manager at the NIH resource center for medical ultrasound transducers at USC. At the NIH-funded project of “A Resource on ultrasonic transducer technology,” we developed high-frequency piezoelectric ultrasound transducers for biomedical ultrasound imaging applications. These novel transducers share the broad bandwidth and high sensitivity and demonstrate a high electromechanical coupling coefficient for piezoelectric materials at high frequencies (> 40 MHz). During my postdoc at NASA/JPL and Caltech, I participated in development of a novel annular ultrasound transducer for wireless communication in high temperature/pressure situations. Also, I served as a Director of Research and Development (R&D) for two mid-size medical ultrasound companies in California and Colorado to develop new diagnostic probe designs and quality control methods according to FDA regulations. Furthermore, as a winner of the most innovative award of the year at USC for a breast cancer surgical, diagnostic tool, my colleagues and I entered a product and business development process with two angel investors for medical device development and commercialization. Moreover, as a co-author of an NSF-grant awarded proposal, I developed a novel digital 3D additive manufacturing method to enhance the fabrication process of complex-geometry medical ultrasound imaging transducers, which paved a new path for the development of any-geometry 3D ultrasonic imaging and therapeutic medical transducers/probes.
