Profile Summary

My research focuses on the structure of materials.  My two major research themes are (1) studies of the structure of amorphous materials using fluctuation electron microscopy, a technique my group has developed based on coherent electron nanodiffraction; and (2) studies of defects and interfaces in crystalline materials and devices using extreme high-resolution imaging and microanalysis.   Within these themes, my group works on a variety of materials systems, spanning metals, semiconductors, superconductors, and complex oxides, and a variety of functional structures, including nanoelectronic, optoelectronic, and spintronic devices, catalysts, and functional interfaces.
