I have been studying for my PhD degree in Energy Resources Engineering at Stanford University since 2011. I studied chemistry for undergraduate and environmental engineering for MS both at Korea Advanced Institute of Science and Technology (KAIST), South Korea.
My research interest is metallic membranes for energy and environmental applications, including composite membrane fabrication, material analyses, membrane gas permeation measurements, and atomic-scale modeling of metallic membrane systems.

Reducing CO2 in the atmosphere and preventing its release from point-source emitters, such as coal and natural gas-fired power plants, is a global challenge measured in gigatons. Capturing CO2 at this scale will require a portfolio of gas-separation technologies to be applied over a range of applications in which the gas mixtures and operating conditions will vary. Chemical scrubbing using absorption is the current state-of-the-art technology. Considerably less attention has been given to other gas-separation technologies, including adsorption and membranes. It will take a range of creative solutions to reduce CO2 at scale, thereby slowing global warming and minimizing its potential negative environmental impacts. This review focuses on the current challenges of adsorption and membrane-separation processes. Technological advancement of these processes will lead to reduced cost, which will enable subsequent adoption for practical scaled-up application.
