Dr. Hee Jung Chang has completed her Ph.D. program in the Department of Chemistry at Stony Brook University in New York, working with Prof. Clare Grey and a particular emphasis of her research work mainly focused on lithium metal anodes. She was able to develop various real time techniques such as NMR, MRI, SEM and X-ray tomography to study lithium ion batteries. She is now working at Pacific Northwest National Laboratory (PNNL) as a postdoctoral research associate and currently focused on sodium metal halide (Na-MH) batteries for the stationary energy storage application.

Research Interests

  • High temperature Na batteries.
  • Stationary energy storage and electric vehicle applications.
  • Development of real-time techniques for energy storage systems.

Education and Credentials

  • Ph.D. Chemistry, Stony Brook University
