Overview

Personal Profile

Katherine Jungjohann is a group manager at NREL. She joined NREL in 2021, after starting her career within the U.S. Department of Energy’s Nanoscale Science Research Centers, including the Center for Integrated Nanotechnologies and the Center for Functional Nanomaterials. Her research began with liquid-cell scanning/transmission electron microscopy (S/TEM) of nanoparticle synthesis and catalytic nanoparticles. During her tenure at Sandia National Laboratories, she worked heavily on lithium metal anode characterization using in situ electrochemical S/TEM and cryogenic electron microscopy methods. In addition, she led the development of a microelectromechanical system (MEMS) device fabrication to advance in situ S/TEM capabilities, which resulted in a patent. Jungjohann has supported research on an array of user projects that required in situ S/TEM (electrical biasing, electrochemistry, heating, heating in liquids, and cryogenic, straining, and environmental TEM). She now supports her group’s role in providing advanced analytical microscopy and imaging characterization to NREL and NREL’s collaborators.
