Won-Ju Cho received a B.S. degree in Electronic Engineering from Kyungpook National University, Daegu, Korea, in 1989; he received his M.S. and Ph.D. degrees in Electronic Engineering from Keio University, Tokyo, Japan, in 1991 and 1994, respectively. In 1994, he joined Hynix Semiconductor Inc., Cheongju-Si, Korea, where he was involved in the advanced process development of memory devices. From 1999 to 2000, he worked at AIST, Tsukuba, Japan, where he developed ultra-low-loss power devices that were fabricated from silicon carbide. From 2000 to 2004, he worked at the Electronics and Telecommunications Research Institute (ETRI), Daejeon, Korea, where he was involved in research on nanoscale silicon MOSFET devices. Recently, he was appointed as a professor in the Department of Electronic Materials Engineering at Kwangwoon University, Seoul, Korea. His current research interests include new electronic devices and materials, simulations, processing, analysis, and bio-devices. Prof. Cho is a recipient of the ETRI Researcher Award for Excellence in 2003, the Korean Institute of Electrical and Electronic Material Engineers Best Paper Award in 2007, the Korean Physical Society Announcement Award for Excellence in 2008, and the Kwangwoon University Grand Prize of Scholarship (Best Performance Study for 5 years) in 2010.
