His research interests are in RF, Analog and Digital IC, Transceiver design and sensors. Prior to that, Kiaei was a professor at Oregon State University (1987-1993), where he taught courses and performed research in RF, Analog, VLSI and Communication Systems. Kiaei has established two Industry-University Cooperative Research Centers: Center for the Design of Analog/Digital ICs (CDADIC) where he was a co-director from 1987-1993, and the Connection One Center at Arizona State University. He has published more than 200 journal and conference papers and holds several patents. From 1993 to 2001, he was a senior member of technical staff with the Wireless Technology Center and Broadband Operations at Motorola. Sayfe Kiaei is a professor in the School of Electrical, Energy and Computer Engineering, the director of the Connection One Center (National Science Foundation (NSF) I/UCRC Center), and Motorola Chair in Analog and RF Integrated Circuits.
