He received B.S. and M.S. degrees in Mechanical and Aerospace Engineering from Seoul National University in 2002 and 2007, respectively, and received his Ph.D. degree in Mechanical Engineering at the University of Michigan in 2013. He served as a research fellow in Electrical Engineering and Computer Science at the University of Michigan in 2013, and worked as a research staff at Samsung Advanced Institute of Technology in 2013-2014. His research interests involve the continuous and scalable nanomanufacturing technologies highlighted by rollable nanofabrication and template-free nanopatterning, and the hybrid functional nanostructures comprising carbon nanotubes, graphene, and metal oxide nanowires, for photonic, electronic, sensing, and energy conversion devices.
