Changzhi Li is Associate Professor of Electrical and Computer Engineering at Texas Tech University, Lubbock, TX, USA, where his research interests include analog circuits, microwave circuits, and biomedical applications of microwave/RF. He is an associate editor for IEEE Transactions on Circuits and Systems II and served as an area editor for the International Journal of Electronics and Communications from 2011 to 2013. He served as the TPC co-chair for the IEEE Wireless and Microwave Technology Conference (WAMICON) in 2012 and 2013. He received the NSF Faculty Early CAREER Award in 2013, the Texas Tech Alumni Association New Faculty Award in 2012, and the IEEE MTT-S Graduate Fellowship Award in 2008. He was a finalist in the Vodafone Wireless Innovation Project competition in 2011 and has received nine best paper awards as author/advisor at IEEE conferences.Mohammad-Reza Tofighi received a B.S. degree from Sharif University of Technology, Iran, in 1989, an M.S. degree from Iran University of Science and Technology, in 1993, and a Ph.D. degree from Drexel University, Philadelphia, PA, in 2001, all in electrical engineering. He is now an Associate Professor of Electrical Engineering at Pennsylvania State University, Harrisburg. His main research interest is on medical and biological applications of RF and microwave, which he has been pursuing for the past eighteen years. In particular, he conducts research on wireless implants and sensors, microwave radiometry and imaging, biomedical antennas and applicators, interaction of microwave with biological tissues, and permittivity measurement using time and frequency domain methods. Dr. Tofighi has been the past chair (2009-2013) of the MTT-10, the technical committee on biological effects and medical applications of RF and microwave of the IEEE Microwave Theory and Techniques (MTT) society. For many years, he has been active in promoting the subject area of medical and biological applications of RF and Microwave within the MTT sponsored conferences. He has also served as a guest editor for two special issues of IEEE Transactions on Microwave Theory and Techniques on the subject area, Oct. 2009 and May 2013 issues.Dominique Schreurs is a full professor at KU Leuven, Leuven, Belgium. Previously, she has been a visiting scientist at Agilent Technologies (USA), Eidgenössische Technische Hochschule Zürich (Switzerland), and the National Institute of Standards and Technology (USA). Dominique's main research interests concern linear and nonlinear characterization and modeling of microwave devices and circuits, as well as linear and nonlinear hybrid and integrated circuit design for telecommunications and biomedical applications. She is the technical chair of ARFTG and serves as the editor of the IEEE Transactions on Microwave Theory and Techniques.Distinguished Professor, National Sun Yat-Sen University, Taiwan.
