Lei Liu (Senior Member, IEEE) received the B.S. and M.S. degrees  from Nanjing University, Nanjing, China, in 1998 and 2001, respectively, and the Ph.D. degree from the University of Virginia, Charlottesville, VA, USA, in 2007, all in electrical engineering.

From 2007 to 2009, he was a Post-Doctoral Research Associate with the Department of Electrical and Computer Engineering, University of Virginia. In 2009, he joined the University of Notre Dame, Notre Dame, IN, USA, where he is currently an Associate Professor of electrical engineering. He has authored or co-authored ~160 journal and conference papers. His current research interests include advanced THz sensing and imaging, tunable and reconfigurable THz circuits and components, THz detectors and mixers, submillimeter-wave and THz device and circuit design, modeling, and testing, quasi-optical techniques, novel THz materials and devices, superconducting electronics, microfabrication and processing.

Dr. Liu served as a Session Chair of the 2006 IEEE Applied Superconductivity Conference, a Session Chair or Co-Chair of the 2015, 2018, 2022, 2023 and 2025 IEEE MTT-S International Microwave Symposium (IMS), and a Student Paper Competition Judge for the 2011 and 2017 IEEE MTT-S IMS. He has been an IEEE MTT-S IMS TPRC member since 2013. He served as a steering committee member and Student Paper Competition Chair of the 2024 IEEE MTT-S IMS (Washington, DC, USA), and he is now serving as a TPC member of the 2026 IEEE International Conference on Infrared, Millimeter, and THz Waves (IRMMW-THz) in Salt Lake City, Utah. Dr. Liu was the recipient of the IEEE MTT-S THz Prize (IEEE Transaction on Terahertz Science and Technology Best Paper Award) in 2019. His students were the recipients of the 2012 IEEE Asia–Pacific Microwave Conference (Taiwan) Student Prize, the 2012 International Conference on Infrared, Millimeter and Terahertz Waves (Wollongong, Australia) Best Student Paper Award, the 2015 IEEE MTT-S Graduate Fellowship Award, the 2019 IEEE MTT-S International Microwave Conference on 5G and Beyond Best Student Paper Award (first place), and the 2024 IEEE International Symposium on Space THz Technology (ISSTT 2024) Best Student Paper Award (2^nd place).
