Professional Background

Microelectronics materials and structures

Research Interests

As devices and nanostructures become ever smaller, the surface or interface to volume ratio becomes so large that these surfaces and interfaces dominate device performance.  My interest has been to develop new methods to fabricate and control these interfaces, develop new tools to characterize them, and finally to use these tools to measure and understand the new properties of the engineered nanomaterials that we have learned to prepare.
