He completed his PhD at TCD under the supervision of Prof William Wright, the head of the School of Engineering.
His 1961 doctoral thesis was a study in mathematically complex solutions for torsional stresses in hollow reinforced concrete beams. He studied with Bernard Carré on the English Electric DEUCE computer at Stafford over the course of 2 summers.
In 1960, Byrne was awarded an Imperial Chemical Industries Research Fellowship.
Career

Byrne was appointed a junior lecturer at the engineering school at TCD in 1963.
Supported by Wright, who campaigned for TCD to buy its first computer in 1962, an
IBM 1620.
Byrne proposed TCD's first evening course in computer programming and systems analysis which ran for two nights a week. The course was industry aligned, and was aimed at young graduates interested in learning these skills. The success of the evening course led to the creation of a BA Mod degree programme. Byrne has been credited with a key role in the development of the computer industry in Ireland from the 1960s onwards through his pioneering courses in computer science and the quality of the graduates produced.
He has also been credited with encouraging more women into the field when it had become predominantly a male discipline.
Byrne became the first head of computer science in TCD when the department was founded in 1969 and was made a Fellow in the same year, becoming Professor of Computer Science in 1973.
He subsequently became a Senior Fellow. When the internet was deployed in Ireland for the first time on 17 June 1991 by the Trinity campus company, IEunet, Byrne was a director. The first Irish

In 2005, Byrne supervised the masters students who created the first digitised copy of the
Library of Trinity College's 1872 Printed Catalogue. He advised on the Library's Stella Project in the 1990s which digitised the Library's periodicals card catalogue, and the Melon Project in the 2000s which was focused on the digitised Accessions Catalogue.
Over the course of his career Byrne collected a large volume of books, publications, and collected examples of hard and software which has now became the core collection of the John Gabriel Byrne Computer Science Collection.
Death and legacy

Byrne retired from TCD in 2003.
He died at a nursing home in
