Jaehun Lee graduated the Department of Materials Science and Engineering in Seoul National University(SNU) in 2012, and currently a Ph.D. candidate working under the guidance of Prof. Ki Tae Nam at SNU. His areas of research include self-assembly of short peptide molecule in 2-D nanostructures, inorganic-peptide hybrid materials, biomaterials hybrid hydrogel, and electrochemical charge transfer in those materials. In recent, his researches focus on proton conducting peptide materials which are applicable to active material in bioelectronics devices.
