About Me
Dong-Kyun Ko is currently an Associate Professor of Electrical and Computer Engineering at NJIT. He received his BS from Yonsei University (Korea, 2005). He received his MS (2007) and PhD (2011) degrees from the University of Pennsylvania. After his PhD, he held a joint chemistry and electrical engineering appointment at MIT as a Postdoctoral Associate. Dong-Kyun's research focuses on colloidal quantum dot-based devices, in which semiconductor nanocrystals with tailored electronic properties are used as fundamental building blocks to construct devices from the bottom-up. This approach provides an opportunity to exploit unique properties arising from nanoscale components and to explore unconventional device concepts and designs.
