Guido Valerio (Senior Member, IEEE) received the M.S. degree (cum laude and Hons.) in electronic engineering and the Ph.D. degree in electromagnetics from La Sapienza University, Rome, Italy, in 2005 and 2009, respectively. From February to August 2008, he was a Visiting Scholar at the University of Houston, Houston, TX, USA. From 2011 to 2014, he was a Researcher at the Institute d’Electronique et de Télécommunications de Rennes (IETR), Rennes, France. Since September 2014, he has been at Sorbonne Université, Paris, France, where he is currently a Professor with the Laboratoire de Genie Electrique et Electronique de Paris. His scientific research interests involve antenna design and numerical methods for wave propagation and scattering in complex structures, namely, periodic Green’s function computation, modal properties of multilayered structures, full-wave methods for SIW, and modeling and design of periodic structures. Dr. Valerio was a recipient of the “Leopold B. Felsen Award for Excellence in Electrodynamics” in 2008; the “Barzilai Prize” for the best paper at the National Italian Congress of Electromagnetism (XVIII RiNEm) in 2010; and the RMTG Award for junior researchers presented at the IEEE Antennas and Propagation Society Symposium, Memphis, TN, USA, in 2014. In 2018 and 2020, he was a coauthor of the best papers in Electromagnetic and Antenna Theory at the European Conference on Antennas and Propagation. In 2022, he was a coauthor of the Best Student Paper Award at the 16th European Conference on Antennas and Propagation. He is serving as an Associate Editor for IEEE Transactions on Antennas and Propagation and IEEE Access journals and is the Main Chair of the COST Action SyMat on “Future communications with higher symmetric engineered artificial materials.”
