Professor Griffiths joined Swansea as an Assistant Lecturer in 1964; he subsequently became a Lecturer (1966), Senior Lecturer (1971), and a Reader (1978), and was Professor of Medieval History from 1982 to 2002. He served as Dean of Admissions between 1990 and 2002, and was a Pro-Vice-Chancellor between 1998 and 2002.
Professor Griffiths was a member of the Royal Commission on the Ancient and Historical Monuments of Wales from 1990, and served as its Chair since 1999-2009. He sat on the Advisory Council on Public Records between 1996 and 1999, and on the Council of the Royal Historical Society between 1987 and 1991, serving as Vice-President between 1992 and 1996.
Professor Griffiths's ongoing research lies in the broad field of politics and society in later medieval Britain. He is particularly interested in perceptions and relationships among the peoples of the British isles, the English monarchy and its dominions, the Lancastrian and Yorkist regimes in fifteenth-century politics, towns and the historic environment in Wales and the borderlands, and Anglo-Welsh society. He is also interested in nineteenth- and twentieth-century historiography of the Middle Ages.
