Eduardo Rojas earned his M.S. and Ph.D. degrees from the University of South Florida, all in Electrical Engineering; in 2014 and 2017, respectively. He joined Embry-Riddle Aeronautical University in 2017, where he is currently an associate professor. His research interests are in microwave/mm-wave circuits and antenna applications of additive manufacturing; and wireless sensing for harsh environments. Rojas is the Director of ERAU’s Wireless Devices and Electromagnetics Laboratory (WIDE Lab www.wide-lab.com). He received a CAREER Award from The National Science Foundation in 2019; the 2020 Most Promising Engineer Award, Ph.D. Education category, from the Great Minds in Stem (GMiS) organization; and ERAU’s 2021 Abas Sivjee Outstanding Research Award. Rojas has more than 40 peer-reviewed publications and 5 U.S. patents. Rojas is a member of the IEEE MTT-S Technical Committees 4, 26, and 29; and the RTCA SC-236 committee for Standards for Wireless Avionics Intra-Communication System (WAIC) within 4200-4400 MHz.
