Coming from a musical family, Christopher studied the piano and cello growing up, playing the latter with the National Youth Orchestra of Great Britain. He began conducting orchestras and operas when studying as a Choral Scholar at Trinity College, Cambridge, going on to study with Jorma Panula in Finland, and privately with Peter Stark. Since graduating he has worked extensively on the music staff of Glyndebourne Festival and Tour; he assisted Music Director Robin Ticciati on Mozart's Die Entführung aus dem Serail and was awarded the Lefever Study Award for work on Britten’s The Turn of the Screw. He works regularly with English Touring Opera and is looking forward to conducting Mozart's Le nozze di Figaro for the company in 2018. Further highlights in opera include Birtwistle's Down by the Greenwood Side for Brighton Festival, the staged premiere of Gerald Barry's La Plus forte and Britten's A Midsummer Night's Dream in Aldeburgh.
He cofounded the Multi-Story Orchestra with composer Kate Whitley in 2011. In 2016 the Orchestra's work was recognised with an RPS Award for their annual summer festival of orchestral music in a Peckham Car Park. Their first performance was The Rite of Spring in 2011, and repertoire since has included symphonies of Beethoven, Brahms and Sibelius, as well as large-scale 20th-century works such as Andriessen’s De Staat and Grisey's Les espaces acoustiques. Outside of Peckham, the Orchestra has played in the Aldeburgh and Brighton festivals and recorded for NMC. In 2016, Christopher and the Multi-Story Orchestra made their BBC Proms debut with a programme of works by Steve Reich.
