Research Interests

The unifying theme in our research group involves the science of miniaturization.  We invent new methods to fabricate micro and nanoscale devices and integrated structures for applications in electronics and medicine. Additionally, since the role of interfaces becomes extremely important as the size of devices decreases, we utilize state-of-the-art experimental tools in surface science to probe interfacial phenomena at the molecular scale. Relevant research topics involve nanoelectronics, non-linear optics, self-assembly, microelectromechanical systems (MEMS), microfluidics, drug delivery and nanomedicine.
