Welcome! I am Rae Eon Kim, a Ph.D. student at POSTECH. Rooted in physical metallurgy, my research develops high-performance heterostructural alloys that go beyond conventional limits by integrating multiple functionalities:

• High tensile strength for mechanical robustness
• Mechanical properties in extreme environments, from cryogenic to high temperature
• High specific strength for lightweight structural applications
• Resistance to hydrogen embrittlement

My vision is to develop next-generation structural materials that are strong, ductile, and multifunctional through heterostructure engineering.
