Dr. Byungchan Han is an Associate Professor at the Department of Chemical and Biomolecular Engineering of Yonsei University in Seoul, Korea. He earned his PhD degree in MIT at the Dept. of Materials Science and Engineering in 2007. He obtained Bachelor and Mater degrees from the Dept. of Nuclear Engineering of Seoul National University. He spent two years in MIT and another two years in Stanford University as a Postdoctoral Research Associate. His research interests are developing emerging energy materials for renewable energy devices such as fuel cells and Li-ion batteries using first principles computational materials science. Recently he is also working for the pyroprocessing technology to recycle spent nuclear fuels. He was introduced as 10 most leading young scientists in Korea, and a deputy Director of the Joint Research Center between DGIST and Lawrence-Berkeley National Laboratory. He was awarded a medal from International Advanced Association of Materials, and got an excellent research award at Yonsei University in 2016. Currently, he is an editorial board of Scientific Reports (Nature Publishing Group) and Frontiers in Condensed Matter Physics, and a Scientific Committee Member at Material science 2017. In Korea he is an Advisory Committee of the Korean Institute of Surface Engineering. His research interests are first principles computational design of high functional materials for renewable energy devices (such as Li-ion batteries, fuel cells, solar cells) and used nuclear fuel pyroprocessing system.
