Principal Research Scientist
Woo-Sang designs mechanically strong and commercially relevant metallic alloys, such as Ni-based superalloy, with high chemical- and corrosion- resistivity for high-temperature energy applications. He is investigating the multi-timescale creep life of alloys from short-term (<5000 hr) to long-term (~100,000 hr) in conjunction with his effort to develop the theoretical models to predict long-term creep life of alloys using short-term behavior.

Principal Research Scientist
Professor, Division of Nano&Information Technology, UST KIST School
Jin-Yoo's research interest lies in the metallic materials' physical and chemical properties that stem from the microstructure. He studies the correlation between the microstructure and the hydrogen-metal interaction in (i) hydrogen storage alloys, (ii) metallic membrane for hydrogen separation, and (iii) hydrogen embrittlement in steels and other alloys. Also, he works on high temperature creep behavior of heat resistant alloys, for examples, type IV failure of the heat affected zone of martensitic heat resistant steels and creep behavior of FCC high entropy alloys.
