Charles  Byrne Author of Evaluating Organization Development

Charles Byrne

Professor Emeritus
University of Massachusetts Lowell

I attended high school and college in Washington, DC, where I was a classmate of Bill Clinton at Georgetown. I got my graduate degrees from the University of Pittsburgh. I retired in 2014 after 42 years as a mathematics professor, first at The Catholic University of America, Washington, DC, and then the University of Massachusetts Lowell. I chaired the department at CUA from 1983 to 1986, and the department at UML from 1987 to 1990. My wife Eileen and I are now enjoying our new horse, Nate.

Subjects: Mathematics


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.
