Dr. Otilia Popescu received the Engineering Diploma and M.S. degree from the Polytechnic Institute of Bucharest, Romania, and the PhD degree from Rutgers University, all in Electrical and Computer Engineering. While at Rutgers her research was conducted at WINLAB in the area of wireless communications. Her research interests are in the general areas of communication systems, control theory, signal processing and engineering education. She is currently an Assistant Professor in the Department of Engineering Technology, Old Dominion University in Norfolk, Virginia, where her teaching covers electrical circuits, systems and signals, and communications courses. She has worked in the past for the University of Texas at Dallas, University of Texas at San Antonio, Rutgers University, and Politehnica University of Bucharest. She is a senior member of the IEEE and participates often in the technical program committee for IEEE conferences. She serves as associate editor for IEEE Communication Letters. In the community, Dr. Popescu is interested in stimulating K-12 students’ interest for excellence in mathematics and problem solving. She serves as local manager for Math Kangaroo International Competition and organizes the competition locally each year in March.
