Kyoseung Sim received a Ph.D. degree in Materials Science and Engineering from the University of Houston in 2018 and earned B.S. (2008) and M.S. (2010) degree in chemistry from Konkuk University. Before he joins UNIST as an assistant professor in 2020, he was a post-doctoral researcher at the University of Houston from 2018 to 2020. He also worked as a researcher at POSTECH (2013-2014) and DGIST (2010-2013). His current research interests are soft material-based electronic devices and advanced applications.
Soft (flexible/stretchable) electronics are highly demanded for a wide range of applications that cannot be easily achieved from traditional rigid/brittle electronics such as e-skin, wearable electronics, bio-implantable devices, nerve interfaces, advanced healthcare system, etc. While many groups are working on structural engineering using intrinsically non-soft materials to fabricate soft electronics through complicate and sophisticated processes and approaches, we mainly focus on developing novel soft materials composite by understanding the chemistry of materials. Besides, we are spending much effort into pursuing the realization of various deformable electronics and innovative applications through interdisciplinary studies.
