Prof. Youn-Sang Bae completed his B. S. (1999), M. S. (2001) and Ph. D. (2006) in chemical engineering from Yonsei University, Korea. His Ph.D. research was about the development of adsorptive separation processes for various applications. After his Ph.D., he worked as a postdoctoral fellow and a research professor at the department of chemical & Biological engineering in Northwestern University, USA. At Northwestern University, he worked on the development of metal-organic frameworks (MOFs) for hydrogen storage and various gas separations. In 2012, he moved to the department of chemical and biomolecular engineering at Yonsei University as an assistant professor. He is currently a full professor at the same department. His research focuses on the development of nanoporous materials for use in adsorption-related applications including capture of greenhouse gases such as CO2 and SF6, storage of methane and hydrogen, industrially important and challenging separations such as olefin/paraffin separation, CO recovery from iron industry and CH4/N2 separation, removal of toxic chemicals such as VOCs and radon, and water purification. Recently, his research has been extended to catalytic conversions, electrocatalytic sensors and mixed-matrix membranes. For the molecular-level understanding of adsorption behaviors in the nanoporous materials, he has been also utilizing various molecular modeling techniques including Monte Carlo simulations, density functional theory calculations, high-throughput screening, and machine learning.
