Biographical Sketch

Yong Kyu Yoon received the B.S. and the M.S. degrees in electrical engineering in 1992 and 1994, respectively, from the Seoul National University, Korea. He also received his M.S. degree in electrical and computer engineering in 1999 from the New Jersey Institute of Technology, Newark, New Jersey. He has been pursuing his Ph.D. degree in electrical and computer engineering at the Georgia Institute of Technology, Atlanta, Georgia since 1999. His research area focuses on developing RF passive components, such as high-Q RF inductors, ferroelectric tunable capacitors, and millimeter wave antennas, and developing 3D MEMS devices for the lab-on-a-chip bio/chemical applications.
