Nanomechanics & Multifunctional Materials Reliability Lab

Welcome to NMMRL !

My name is Jong-hyoung Kim. I am an assistant professor at Pukyong National University, Department of Materials Science and Engineering (국립부경대학교 융합소재공학부 재료공학전공). 

As next-generation devices increasingly rely on heterogeneous material systems, the reliability of interfaces operating under complex, dynamic, and harsh in-service environments has become a defining challenge for future technologies.

Our research vision centers on interface reliability across scales and environments — understanding how materials and interfaces deform, evolve, and fail under realistic operating conditions. We pursue an experimentally grounded approach by developing small-scale nanomechanical characterization techniques, full-field deformation metrology, and in-situ/operando experimental platforms that enable direct observation of localized mechanical behavior and interfacial degradation. In parallel, computational mechanics and AI-assisted frameworks are integrated to accelerate property extraction, interpret complex experimental data, and guide the design of reliable multifunctional systems.

Through this integrated methodology, our research aims to establish next-generation reliable material and device systems for applications including microelectronic packaging, wearable and bio-integrated devices, architected functional materials, and extreme-environment platforms operating under non-ambient and in-service conditions.
