Kwang-Jin Koh (S’06–M’09) received the B.S. degree in electronic engineering (with first-place honors) from Chung-Ang University, Seoul, Korea, in 1999, the M.S. degree in electrical engineering from the Korea Advanced Institute of Science and Technology (KAIST), Daejeon, Korea, in 2001, and the Ph.D. degree in electrical and computer engineering from the University of California at San Diego, La Jolla, in 2008. In November 2011, he joined the Electrical and Computer Engineering Department, Virginia Polytechnic Institute and State University (Virginia Tech), Blacksburg, as an Assistant Professor. From 2001 to 2004, he was with the Electronics and Telecommunications Research Institute (ETRI), Daejeon, Korea, where he was engaged in the research and development of RF and analog CMOS integrated circuits for wireless communication systems. From 2008 to 2010, he was with the Portland Technology Group (PTD), Intel Corporation, as a Senior Engineer, where he was involved in the development of voltage-controlled oscillators (VCOs) and phase-locked loops (PLLs) in Intel 32- and 22-nm CMOS processes for Intel microprocessors and radios applications. From 2010 to 2011, he was with the Broadcom Corporation, as a Senior Staff Scientist, where he developed RF integrated circuits (RFICs) for digital TV tuner systems-on-a-chip. His research interests include analog, RF and millimeter-wave integrated circuits and systems wireless communications, radars, and imaging applications. 

Mr. Koh was the recipient of the 2002 Best Paper Award of the IEEE Solid-State Circuits Society and Electron Device Society, Seoul Chapter. His Ph.D. works on integrated phased arrays on silicon technologies have been reported to the U.S. Pentagon as part of a Defense Advanced Research Projects Agency (DARPA) War Report as one of the major accomplishments of 2007. He was also the recipient of the 2010 Best Team of the Year Award of the Teledyne Scientific Corporation (formerly the Rockwell Scientific Corporation), and 2012 Virginia Tech ICTAS Junior Faculty Research Award.
