Joseph took up the post of Sub-Organist of Durham Cathedral in September 2019.

As Sub-Organist, Joseph is the principal accompanist to the Cathedral Choir, playing the organ for daily services in addition to the choir's schedule of broadcasts, concerts, recordings and tours. He also assists the Master of the Choristers in his work conducting the choir, and recruiting and training the choristers.

Prior to his appointment at Durham, Joseph was Assistant Master of the Music at St Mary's Episcopal Cathedral in Edinburgh, where he accompanied the Cathedral Choir in its round of daily services, on a Delphian recording of the choral works of Kenneth Leighton, and on a number of continental tours. He also conducted the choir live on BBC Radio 3. He continues to serve as Vice-President of the Edinburgh Society of Organists.

Born in Grantham, Joseph held the Organ Scholarship at St George's Chapel, Windsor Castle, before winning a scholarship to the Royal Academy of Music. As a prizewinning student of David Titterington, Joseph performed in London's major venues and worked under conductors Marin Alsop, Yan Pascal Tortelier and Trevor Pinnock. Concurrent with his Academy studies, Joseph successively held organ scholarships at the Chapel Royal, Hampton Court Palace; the London Oratory; and St Paul's Cathedral. He graduated with a first-class degree in 2017, also being presented one of the Academy's coveted Regency Awards for 'notable achievement'. 

Aside from his work at the Cathedral, Joseph maintains an active performance schedule, with recent and forthcoming concerts across the UK and in Germany, and also enjoys dedicating time to organ teaching.
