Kwansoo Chung received his PhD from Stanford University, BS and MS from Seoul National University. He is a Professor of Materials Science and Engineering in Seoul National University. His research focuses on the area of Mechanics of materials and non-linear continuum/computational mechanics on thermo-mechanical problems based on plasticity, visco-elasticity, elasticity and heat transfer, and process design and analysis for sheet metals, glasses and fiber-reinforced composites. He has authored and coauthored more than 300 papers in peer-reviewed journals and cited over 5000 times, also holds 4 US patents. Myoung-Gyu Lee recevied his PhD from Seoul National University. He is a Professor of Materials Science and Engineering in Seoul National University. His research interests focus on computational plasticity, mechanics of materials including finite element modeling of advanced structure materials, multi-scale modeling and experiment that reveal deformation mechanism of materials under complex strain path changes.  He is co-authored for over 200 journal articles and 2 proceedings volumes, 3 book chapters in the areas of plasticity theory, advanced constitutive modeling and finite element simulations.  He received the 2014 International Journal of Plasticity Award for excellent contribution to the field of plasticity.
