Dr. Chang received B.S. and M.S. in Avionics from the Korea Aerospace University in 1993, and 1995 respectively. He received M.S. in Electrical Engineering at Columbia University in 2002 and Ph.D. from the Electrical and Computer Engineering (E.C.E) at the Georgia Institute of Technology (Georgia Tech) in 2007.
Currently, he is an Associate Professor in Electrical Engineering at Kennesaw State University and an Adjunct Professor in E.C.E at Georgia Tech. He is also an active member of Communications Systems Center at Georgia Tech and leading a joint Vehicular Ad-hoc Networking (VANET) research laboratory between the two universities with Ph.D. students and research staffs since 2007.
In 1996, he instructed air force officers in the Air Force Artillery School for three years in Korea, and worked at Bell Labs in 2002. He is also the author of the book, “Robust Mobile Networking” published in 2008.
His research interest includes the modeling and the optimization of wireless mobile networks with an emphasis on the implementation of wireless communication systems for Wireless Multimedia Communications, Vehicular Ad Hoc Networks (VANETs), and Intelligent Transportation Systems (ITS).
Dr. Chang is proposing a new paradigm, "Sustainable Mobile Networking" that improves sustainable environment by using intelligent mobile communication technology to reduce traffic congestion and air pollution and enhance transportation mobility and safety.
