In 2009 Felix took up a postgraduate place at the Royal Academy of Music in London to study choral conducting with Patrick Russill and Paul Brough. He graduated in 2011 obtaining a MMus with distinction, and was awarded the Academy’s coveted premier prix, the DipRAM, for outstanding performance in his final recital, as well as the Sir Thomas Armstrong Prize and Irene Burcher Prize. He also obtained the LRAM diploma in choral conducting pedagogy. His dissertation, on the adaptation of Gregorian chant for liturgical use in Chinese, was commended as outstanding and is now leading towards the preparation of a Chinese Gradual. Felix has taken masterclasses with Jeremy Summerly, David Hill, Ben Parry, Roland Börger, James O'Donnell, Simon Carrington, Andrew Carwood and Helmuth Rilling with major choirs including the BBC Singers and the Cardinall’s Musick.

He also led the Royal Academy of Music Chamber Choir in the presence of TRH the Duke and Duchess of Gloucester at a Choral Evensong at the Chapel Royal, St James's Palace in 2011.
