Ryann Rupp, Ph.D.

Research Scientist

Research Areas:


Dr. Ryann Rupp is a Research Scientist in the Materials Science and Engineering department at Idaho National Laboratory. Her primary research interests involve the relationships between processing, microstructure, and mechanical properties. She specializes in materials characterization as well as high temperature structural materials for nuclear and concentrated solar power applications. She has a strong background in ASME Boiler and Pressure Vessel Code qualification. One of her current research focuses is investigating the impact of advanced manufacturing on elevated-temperature mechanical properties for nuclear applications. Dr. Rupp graduated from the University of Texas at Austin with a Ph.D. in Materials Science and Engineering.


​Ph.D., Materials Science and Engineering- The University of Texas at Austin.
