  • I am searching for talented and enthusiastic students to work with! Feel free to contact me if you are interested in embedded and intelligent computing systems research. Before you do so, please take a look at my specific research areas and publications. Preference will be given to students with strong programming skills and some level of knowledge in embedded systems and/or machine learning. I currently have open positions for Ph.D., masters, and undergraduate research students. 

JeongGil Ko received his Bachelors in Engineering (B.Eng.) degree in computer science and engineering from Korea University in 2007. He received his Master of Science in Engineering (M.S.E.) and Doctor of Philosophy (Ph.D.) degrees in Computer Science from the Johns Hopkins University in 2009 and 2012, respectively. At Johns Hopkins, JeongGil Ko was a member of the Hopkins interNetworking Research Group (HiNRG) led by Dr. Andreas Terzis. In 2010, he was at the Stanford Information Networking Group (SING) with Dr. Philip Levis at Stanford University as a visiting researcher. From June 2012 to August 2015, JeongGil Ko was a senior researcher at the Electronics and Telecommunications Research Institute (ETRI).
