Robert (Bob) Johnk (M’91 – SM’07) received his Ph.D. degree in Electrical Engineering at the University of Colorado in 1990, where he specialized in electromagnetics and antennas. Bob is currently a research engineer at the Institute for Telecommunication Sciences (NTIA/ITS) where he is engaged in advancing the state of the art in radio-channel propagation measurements/analysis and mentoring new engineers in the art of measurement science. During the development of the FirstNet National Public Safety Radio System, Bob conducted research on in-building wireless propagation and methods for improving in-building public safety communications. Prior to joining NTIA/ITS in 2007, he worked at the National Institute of Standards and Technology (NIST) in Boulder, Colorado for 17 years, where he was the leader of the time-domain fields project. Bob has received best paper awards from the IEEE EMC Society, NTIA, and NIST. In 2011, Bob received the IEEE EMC Society’s Technical Achievement Award for his work “in the development of free-space time-domain measurement techniques”. Bob has also received a U.S. Department of Commerce Silver Medal award for his work in Public Safety communications. Bob is a Life Senior member of the IEEE and a member of both Eta Kappa Nu and Tau Beta Pi.
