Since the fall of 2012, Dr. Refai has served as Professor for OU at the school of Electrical and Computer Engineering (ECE) Telecommunication Program in Tulsa, Oklahoma. Dr. Refai’s work is currently focused in the development of optical wireless mobile communication system using free space optics, cognitive radios and networks, vehicle-to-vehicle communication systems, and auto-collision avoidance systems. He is founder and director of the Wireless Electromagnetic Compliance and Design (WECAD) Center at OU-Tulsa. WECAD’s mission is to conduct basic and applied research examining medical device coexistence with various RF wireless systems and technologies, as well as validating electronic and electromagnetic compatibility. Dr. Refai is past IEEE ComSoc Tulsa Chapter President and served as the organization’s North American Distinguished Lecturer Tour Coordinator.

Dr. Refai has published more than 162 referred papers for national and international conferences. He has authored 56 journal articles, and a book chapter.

During Dr. Refai’s tenure at OU-Tulsa, he has developed and taught five new courses, including RF Microelectronics, Digital Signal Processing, Wireless Communication, Wireless Networks and Standards, Network Management and Design, and Telecom Laboratory. He supervised and successfully chaired 48 MS ECE students and 19 ECE PhD students.

Dr. Refai is also the founder and director of Innovative Traffic Systems and Solutions LLC—a company that develops computing and communication systems for use in intelligent transportation and highway systems. Further information is available at the following link:
