Jorge L. Salazar-Cerreño received a B.S. in ECE from the University Antenor Orrego, Trujillo, Peru, in 1994. He received an M.S. degree in ECE from the University of Puerto Rico, Mayaguez (UPRM) in 2002. In 2011, he received his Ph.D. degree in ECE from the University of Massachusetts, Amherst. His Ph.D. research focused on the development of a low-cost dual-polarized active phased array antennas (APAA) for the Engineering Research Center for Collaborative Adaptive Sensing of the Atmosphere (CASA). After graduation, Dr. Salazar-Cerreño was awarded a prestigious National Center for Atmospheric Research (NCAR) Advanced Study Program (ASP) postdoctoral fellowship. At NCAR, he worked at the Earth Observing Laboratory (EOL) division developing state-of-the-art airborne radar technology for two-dimensional, electronically scanned, dual-pol phased array radars for atmospheric research. This is a critical tool for studying weather and related hazards, especially for retrieving dynamic and microphysical characteristics of clouds and precipitation over rugged terrain or the open ocean, where other radar systems can have major limitations. In July 2014, he joined the Advanced Radar Research Center (ARRC) at The University of Oklahoma as a research scientist. He became an associate professor at the School of Electrical and Computer Engineering in August 2021. His research interests include high-performance, broadband antennas for dual-polarized phased array radar applications; array antenna architecture for reconfigurable radar systems; APAA; Tx/Rx modules; radome EM modeling; RF and hardware development for characterizing and calibrating APAA and millimeter-wave antennas. In 2019, Dr. Salazar was awarded the William H. Barkow Presidential Professorship. Presidential Professors inspire their students, mentor their undergraduate and graduate students in the process of research and creative scholarly activity within their discipline and exemplify to their students and their colleagues the ideals of a scholar through their endeavors in teaching; research and creative scholarly activity; and professional and university service and public outreach. Dr. Salazar is recipient of the 2022 OU Outstanding Faculty Award of the year, 2021-2022 OU Annual Award for Excellence in Research Grants. Also awarded with the First Paper Award on Antenna Measurements and Applications in 2021.Dr. Salazar is a senior member of the IEEE and currently serves as a reviewer for IEEE Transactions on Antennas and Propagation (TAP), IET Microwaves, Antennas and Propagation (IET), the Journal of Atmospheric and Oceanic Technology (JTECH), IEEE Transactions on Geoscience and Remote Sensing (TGARS), John Wiley and Sons, and the Radio Science Journal. https://www.ou-arrc-paard.com/.
