PNNL

Hyoju Park is a materials scientist in the Physical Sciences Division at Pacific Northwest National Laboratory (PNNL). She received her BS and PhD in materials science and engineering from the Ulsan National Institute of Science and Technology in South Korea. Before joining PNNL in 2022, Park was a postdoctoral researcher at the Texas Materials Institute, University of Texas at Austin.

Her research is centered on the atomic-scale structural characterization of next-generation energy materials. Park investigates the fundamental structure–function relationships of energy materials using a range of advanced atomic-scale electron microscopy techniques.
