Following graduation in 2001, Jonathan joined the Applied Modelling and Computation Group at Imperial College London, completing a PhD in Geophysics in 2004. Meanwhile he worked as a freelance singer, continuing to perform regularly across the UK in concerts and opera and studying singing with Margaret Lobo. In 2007 he decided to change things around, beginning studies at the Guildhall School of Music and Drama and working part-time at ICL with the aim of pushing forward his singing career into new areas. He spent a rewarding year at the Guildhall, studying with Robert Dean and inspired by the then Head of Vocal Studies Robin Newton. He graduated with distinction in 2008 and has since taken on two professional opera roles and numerous other projects, as well as becoming a very proud father.

Jonathan's performance repertoire spans the centuries, from Gombert and Gesualdo through Bach, Handel and Mozart, to the contemporary music of Fox, Skempton, Finnissy, Lutyens, Scelsi, Sciarrino, Xenakis, Ferneyhough and Rihm. Now becoming well-known in the contemporary music world, in 2008 Jonathan has given premier performances of Legion by Edward Nesbit using the award-winning poetry of David Harsent and Wrack by Rupert Cross, as well as Richard Baker's song cycle Slow passage, low prospect. He sings regularly with Exaudi, and through 2009-10 will be working on projects with IRCAM Paris, including a major new work by Gérard Pesson.
