Douglas A. Gray (M'82) was born in the U.K. in 1946. He received fire B.Sc. and Ph.D. degrees in mathematical physics from the University of Adelaide, South Australia, in 1969 and 1974, respectively.From 1973 to 1993 he was with the Australian Defence Science and Technology Organization applying signal processing to sonar and electronic warfare. From 1977 to 1979 he was a visiting scientist at the Royal Aircraft Establishment, U.K. and in 1985 was a visiting fellow at the Australian National University, Australia. He is currently Professor of Sensor Signal Processing at the University of Adelaide, South Australia and Deputy Director of the Cooperative Research Centre for Sensor Signal and Information Processing. His research interests are in the application of signal processing to sonar and electronic warfare, particularly in adaptive processes, beamforming and signal sorting and classification techniques.
