Dr. Hellen Jiang is a materials scientist in the Applied Materials Processing group in EED. She assists the group by developing various materials and processing methods for different applications via understanding of processing-microstructure-properties relationships. Her current projects include developing soft magnetic materials, lightweight materials, and steels using different manufacturing techniques. Prior to joining PNNL in 2014, she researched optimizing rare-earth and rare-earth-free magnetic materials produced using non-equilibrium processing by tuning alloy compositions and processing parameters. She has extensive experience in magnetic materials design and selection and prediction of properties using microstructural features. She has presented over 20 talks at various professional conferences and workshops.
