Donguk Nam

Dr. Donguk Nam received his Ph.D. (2014) and M.S. (2012) degrees both in the Department of Electrical Engineering from Stanford University, and obtained a B.Eng. degree from Korea University (2009). After working as a postdoctoral scholar at Stanford University for one year, he joined Inha University, South Korea, as an Assistant Professor. In Aug 2017, he joined NTU as an Assistant Professor. His research works focus on developing quantum photonic devices and systems for integrated optical and quantum computing technologies. His research group has constantly published research outputs in high-impact journals including Nature Communications, which have been highlighted by a number of media and magazines including Channel NewsAsia (CNA) and Optics and Photonics News (OPN). Dr. Nam has served and is currently serving as a committee chair and member for several top international conferences such as CLEO, IEEE SUM, ECS Meetings, etc. He has also delivered 10+ invited talks at several top conferences including SPIE Photonics West and CLEO. He is currently serving as a Guest Editor for a special feature on 2D photonics at Optical Materials Express and also as an Associate Editor at Journal of the Korean Physical Society (JKPS). His current research group has 10+ postdocs/staff/PhD students, who are supported by government funding from NRF, MOE, and ASTAR.
