Jungjohann is Group Manager of the Analytical Microscopy and Imaging Sciences group at NREL.
Research
Jungjohann’s research focuses on in-situ transmission electron microscopy imaging of dynamic processes and interfacial phenomena, with primary expertise in energy storage systems. She will bring to REMIND her knowledge of coupled environmental imaging and property measurements during nanoscale imaging to observe site-selective electrochemical transformations with control over the environment, temperature, biasing, pushing limits of spatial and temporal resolution.
