Professor of Electrical and Computer Engineering

William T. Joines earned the BS degree from North Carolina State University, MS, and PhD degrees from Duke University (all in electrical engineering) in 1959, 1961, and 1964, respectively. After high school and before college he served for four year in the United States Air Force (1951-1955) as an airborne radar technician. From 1959 to 1966 he was a Member of the Technical Staff of Bell Telephone Laboratories. He joined the Electrical Engineering Department of Duke University as an Assistant Professor in 1966. He was appointed as an Associate Professor in 1968 and a Full Professor in 1979. His current research interests include electromagnetic field and wave interactions with materials and structures. He is a member of the Tau Beta Pi, Eta Kappa Nu, Phi Kappa Phi, and Sigma Xi, honor societies. He is a Life Senior Member of IEEE, and he has earned Scientific and Technical Achievement Awards from the U.S. Environmental Protection Agency in 1982, 1985, and 1990.
