The current focus of my research group is on the Design of High-Precision High-Bandwidth Motion Systems for macro, micro and nano scale applications. Our design philosophy is based on the principles of precision engineering and mechatronics, and we heavily rely on the engineering disciplines of kinematics, mechanics, dynamics and controls to achieve high system performance. Examples of ongoing work include
- Flexure Mechanism Design Theory
- Nanopositioning Stages for Micro and Nano Manufacturing
- MEMS / NEMS Sensors and Actuators
- High Dexterity Laparoscopic Tools for Minimally Invasive Surgery
