After winning the Edward Boyle Scholarship, Jill studied in Vienna with Paul Badura-Skoda and performed throughout Austria as soloist and chamber player.

Jill has now performed extensively throughout the UK, including at the Royal Festival Hall. She has given concerto performances with the City of Bradford CO and the Manchester Camerata, with whom she appeared at the Last Night of the Proms in Leeds Town Hall. Jill is a Steinway Artist and has given a recital in Steinway Hall to promote the 32 Short Films on Glenn Gould. Jill has performed abroad in Switzerland, the Czech Republic, and in Amsterdam and Den Haag as part of the Anglo-Dutch Piano Platform.

She has undertaken frequent freelance engagements with the LSO, working with, among others, Vadim Repin, Kent Nagano, Yuri Bashmet, Michael Tilson-Thomas, John Adams and Sir Colin Davis.

During the 2001-2 season Jill gave a particularly well-received performance of Bach's Goldberg Variations in the South Bank's 'Fresh' series, and made two other appearances at the Purcell Room, also making her Wigmore Hall chamber debut.
