Lynch spent much of his early life in Carrog in northern Wales and obtained a degree at Bangor University.

[2] Lynch, however, became best known for his academic career and his scholarly work on Welsh literary history.

[1][3] His scholarly contributions have focused on medieval and early modern Welsh poetry, notably that of the Gogynfeirdd or Poets of the Princes.

On the topic of prophecy in Welsh poetry, he has both led a research project (2002-2005) and read a paper in the 2004 J. E. Caerwyn and Gwen Williams Memorial Lecture.

[1][3] In 2001, Lynch published Cywion Nell, a Welsh adaptation of Robert Barnard's 1981 novel Mother's Boys.
