I was born in South Korea and received B.S. (2013), M.S. (2015) and Ph.D. (2018) in Material Science and Engineering from Kookmin University. For my master and doctoral degree, I joined the group of Prof. Heeman Choe (in Kookmin University) working on the processing and characterization of porous materials. I have performed studies on the fabrication/microstructural/mechanical characterization of metal foam (Cu, Co, and alloy), and their potential application for lithium-ion batteries. In 2014 and 2016, I was a visiting scholar in the Dunand's group doing research on freeze-casting and ink-printing of metals. Now in 2021 at NU, I study the manufacturing of metallic foams via freeze-casting, 3D-printing and Selective laser melting
