Biography

Jon Ihlefeld is an Associate Professor in the Materials Science and Engineering and Electrical and Computer Engineering Departments at the University of Virginia. He joined UVa in 2017 following a career at Sandia National Laboratories in Albuquerque, NM where he held positions of Senior, Principal, and Distinguished Member of the Technical Staff in the Materials Science and Engineering Center. His research group studies the linkage between processing, structure, and resulting properties in ferroelectrics, dielectrics, and ion-conducting thin films. His group then utilizes this understanding to enable materials integration resulting in novel electronic, thermal, or optical functionality and devices. This includes demonstration of active phonon transport regulation using ferroelectrics, methods to interrogate nanoscale ferroelectric domain structure in active devices, property enhancement via improved material integration, and fast ion conducting thin films for energy storage, among others.
