Embedded Files
Our lab is dedicated to both cutting-edge research and undergraduate student training. We are fascinated by the rapid evolution of our modern electronic gadgets such as iPhones, google glasses, hard disc drives..., and we are interested in exploring the frontier of science and engineering that can drive more future innovations of such kind. In particular, we care much about the energy-efficiency, miniaturization, and human-friendliness of future electronic gadgets.
