I received my PhD from the University of Pittsburgh in 1972 in functional analysis and topology. Around 1979 I began collaborating with friends at the Naval Research Laboratory on sonar signal processing. Shortly thereafter I met Mike Fiddy, of the Physics Department, University of London, with whom I have collaborated for several decades. In 1990 I began visiting the Department of Radiology, University of Massachusetts Medical School. I have worked with Mike King and his group at UMMed since that time, primarily on algorithms for tomographic image reconstruction.
