Research Overview:

My primary research interest is the bioinstrumentation with the focus on ultrasound applications. Ultrasound is a mechanical wave and its behavior is governed by the medium properties. Therefore it is valuable physical modality in the assessment of material properties such as mechanical strength and internal material structure. We have developed scanning confocal ultrasound device for bone properties imaging to detect the mechanical properties of bone as an alternative means in the early diagnosis of osteoporosis. The device is now evaluated in the NASA's bed rest project studying the response of muscular-skeleton system of astronauts under microgravity in space.

My other research interest is the application of the virtual instrumentation and embedded system technologies in biomedical engineering. Virtual insturmentation is a layer of hardware and software built on the general purpose computer to create the instrumentation that is equivalent to the traditional custom-designed electronic device. An embedded system is a customed designed computer system specializing in predefined tasks. It has a wide application in small bioinstrument where the use of general purpose computer is not practical. As an example, we are now developing a portable artificial vision system based on the embedded microcontroller technology. The system applies electric stimulations through implanted electrode arrays on the visual cortex surface of the blind patients and creates phosphene image that can restore visual perception of the patients.
