He spent his 36 year career in the Electrical and Computer Engineering Department of the University of Florida (Gainesville, FL). In 1968 he was appointed Assistant Professor and he rose through the ranks to become Professor in 1984. From 1990 to 2004 he was the Associate Chair of the ECE Department at UF. Since 2004 he has been retired as Professor Emeritus.

His field of interest is in communications systems, with expertise in modulation theory and applications to wireless communication systems. At one time or another, he taught each of the different undergraduate and graduate communication courses in the UF ECE Department.
