| Biography |
Gih-Keong Lau received his Ph.D. degree in 2007 from Delft University of Technology (TU Delft), Netherlands, for his research work on polymeric micro-actuators. He obtained the B.Eng (with First Class Honour) and M. Eng degrees of mechanical engineering,in 1998 and 2001 respectively, from the Nanyang Technological University (NTU), Singapore.
He join the School of Mechanical and Aerospace Engineering, NTU, as Assistant Professor, since 2008. Before that, he worked with TU Delft as a Ph.D researcher (Promovendi in Dutch) for 2004 to 2007. From 2001 to 2003, he worked as a research associate with the Centre for Mechanics of Microsystems at NTU, on the topics of topology optimization of compliant mechanisms, optimum mechanical design and piezoelectric actuators for hard disk drives. In addition, he has been serving as a reviewer for the Journal of Micromechanics and Microengineering and the journal of Sensors and Actuators since 2005. |
| Research Interests |
Dr Lau's areas are micro-and-nano electro-mechanical systems (MEMS/NEMS), actuator design, micro-fabrication, multiphysics modeling and topology optimization. He has extensive experiences with various actuators, such as electro-thermal, piezoelectric, electrostrictive, and dielectric. Since 2004 at Delft University of Technology, the Netherlands, he has pioneered the work on a new class of polymer micro-actuators with embedding skeletons. His research on the polymer micro-actuators has been recognized with two best poster awards in the workshops of Micro-Mechanics Europe (MME) in 2005 and 2006. In addition, the work was selected and highlighted in the Virtual Journal of Nano-Science and Technology. A Dutch patent application on this inventive actuator design was filed in the Netherlands.
His current research focuses on polymer actuators (based on electro-active polymer), composite design, and their micro-fabrication. |
