Takaaki Koyanagi

Bio

Takaaki Koyanagi joined ORNL in 2013 as a Postdoctoral fellow and is an R&D staff in Radiation Effects and Microstructural Analysis Group of Materials Science & Technology Division, Physical Science Directorate. His research interests include the development and characterization of refractory materials and their composites for high-temperature and severe-environment applications. This emphasizes the effects of neutron irradiation on the mechanical properties and microstructure of ceramics and fiber reinforced composites, highlighting ceramics matric composites and high temperature materials for nuclear fusion and fission applications. He received an Office of Science Early Career Award to develop a mechanistic framework for additive manufacturing of highly radiation resistant SiC for nuclear fusion applications. He has been leading “Development and Applications of Advanced Ceramics and Composites for Nuclear Fission and Fusion Energy Systems” symposium at International Conference & Exposition on Advanced Ceramics and Composites since 2019.
