He was elected as a Fellow of University College, Oxford in 1784. From 22 January 1808, he was Master of the College until his death in 1821. Shelley was called in to see Griffith and a number of college fellows on 25 March 1811.
When Griffith asked Shelley if the pamphlet was his, Shelley remained silent.
Later that day, a notice appeared on the Hall door, signed by Griffith and the Dean, George Rowley (who succeeded Griffith as Master of the college), stating that Shelley and Hogg were expelled from the college. Griffith was interested in art and architecture.
He was responsible for the south side of the main quadrangle at University College when it was refaced in 1802, including the dining hall and chapel. In 1811, he designed the vestry for the church in Melsonby.
There is a watercolour by him of the Vale of Conway in the Victoria & Albert Museum, London.
He was a prebendary at Gloucester from 1816. At Gloucester Cathedral, he designed the Gothic choir screen, erected in 1820. They lived together in the Master"s Lodgings.
