钟灵 发表于：2008-12-4 14:23:50W. Marshall Leach, Jr., received B.S. and M.S. degrees
in electrical engineering from the University of South
Carolina, Columbia, in 1962 and 1964, and a Ph.D. degree in
electrical engineering from the Georgia Institute of
Technology, Atlanta, in 1972.
In 1964 he worked at NASA in Hampton, Virginia. From 1965 to 1968 he served as an officer in the U.S. Air Force.
Since 1972 he has been a faculty member at the Georgia
Institute of Technology where he is presently associate
professor of electrical engineering. His interests are applied
electromagnetics, audio and electroacoustics. and electronic
circuit design.
Dr. Leach is a member of the IEEE, the Audio Engineering
Society, Sigma Xi, Tau Beta Pi, Eta Kappa No, Omicron Delta
Kappa, and Phi Beta Kappa.
