Professor Menq’s research has focused on physical understanding and mathematical modeling of linear/nonlinear dynamic systems and of the dynamic interactions between these systems, including probes and manipulators, and the associated biological samples or engineered objects. He has used advanced mathematical models, modern sensing/actuation techniques, and fundamental engineering principles to design and realize novel engineered systems and one-of-a-kind instruments. He has also used high-speed electronics, e.g., FPGA, along with state-of-the-art digital control techniques and real-time computation to achieve superior performance relevant to three distinct research areas, i.e., 1) precision engineering and manufacturing at conventional length scale, 2) manipulation at micrometer and nanometer scales, and 3) one-of-a-kind probing systems and instruments to enable controlled probing and manipulation of biological systems.
