Research Interests

Solving problems in bridging the gap between scientific findings and engineering innovations: developing novel manufacturing processes for newly-developed materials such as ink jet printing of PZT material for MEMS and deterministic carbon nanotube assembly, designing and realizing new products at micro- and nano-scales, which include muscle inspired actuators and MEMS energy harvesters.
