Biography
Yusun 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 (ECE)
at the Georgia Institute of Technology in
2007. Currently, he is an Assistant Professor in Division of Engineering at Southern Polytechnic State University and an Adjunct Professor in ECE
at the Georgia Institute of Technology. He is also an active member of Communications
Systems Center . 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).
Yusun 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.
