Professor Young-Chul Lee received his Master and PhD degrees in Chemical and Biomolecular Engineering from Korea Advanced Institute & Science Technology (KAIST), Daejeon in February 2011. From 2011 to 2013, he worked as a postdoctoral researcher in the Department of Chemical and Biochemical Engineering, Chosun University and KAIST. Then, he worked as a research professor from 2013 to 2014 at Inha University, South Korea. Currently, he has been working as an associate professor in the Department of BioNano Technology, Gachon University, South Korea, since April 2014. His research interests are inorganic–organic nanoparticles, especially antioxidant or redox nanoparticles (sub-nanoparticles) for biological, environmental, and cosmetic applications using aminoclays, hydrogels, and 2D layered materials. In addition, his research is focusing on cathode and anode materials for sodium-ion batteries.
