Biography
Professor Shen's general research areas include vibration, sensing, and actuation. Currently, his research focuses on the following three subjects: (a) hard disk drive (HDD) vibration, (b) spindle and rotor dynamics, and (c) PZT thin-film micro-actuators and sensors. In the area of HDD vibration, specific research topics include (a) vibration analysis of hard disk drives under long seeks and settles, and (b) spindle motor vibration at various temperatures. In the area of spindle and rotor dynamics, Professor Shen is developing computational algorithms to predict vibration and understand the physics of complex rotating machines, such as turbine engines and propellers. Specific research topics include (a) vibration of spinning cyclic symmetric rotors and (b) vibration of spinning mistuned rotors. In the areas of PZT thin-film devices, the research objective is to develop micro-sensors and actuators for future medical devices. Specific research topics include (a) micro-actuators for hybrid cochlear implants and (b) micro-sensors for totally implantable cochlear prostheses.
