As a postdoctoral researcher at NREL, Karen Heinselman studies synthesis and characterization of novel nitride thin films, device fabrication for high-temperature applications, and Rutherford backscattering spectroscopy to determine composition of various films. She came to NREL at the end of 2017 as a post-doctoral researcher. She earned her doctorate degree in materials science and engineering at Cornell University, studying under James Richard Shealy. Her doctoral work focused on using low-pressure metal organic chemical vapor deposition to epitaxially grow AlN on silicon.
