Juyul Lee received his Ph.D. degree in electrical engineering from the University of Minnesota, Twin Cities, USA, in 2010. He was with the Agency for Defense Development (ADD), Republic of Korea, from 1998 to 2000. Since 2000, he has been with the Electronics and Telecommunications Research Institute (ETRI), Republic of Korea, where he is currently a Principal Researcher in the Radio Research Division.

His research interests include wireless channel modeling, millimeter-wave and sub-terahertz propagation, machine learning, and information theory. He has contributed to ITU-R recommendations and reports in Study Group 3 (Propagation), particularly in the development and extension of propagation models for higher frequency bands based on measurement-driven studies. He is currently the Chairperson of the ITU-R Correspondence Group 3K-6, which is responsible for studying the impact of higher frequencies (up to 450 GHz) on propagation models and related characteristics.

Dr. Lee has received several honors, including the Best Paper Award from the ETRI Journal in 2020 and the Outstanding Standardization Activity Award from the Korean National Radio Research Agency in 2018. He is a Senior Member of the IEEE.
