Gerald currently maintains a busy schedule as a freelance performer and teacher to many budding musicians. In Singapore, he has performed and collaborated with the Singapore Symphony Orchestra, The Philharmonic Orchestra, re:SOUND Collective, ADDO Chamber Orchestra and the Yong Siew Toh Conservatory of Music. His recent continuo engagements include Pergolesi's and Scarlatti's Stabat Maters, Bach Cantatas and Handel's Acis and Galatea. In 2015, he directed at the Esplanade an evening of rarely heard 18th-century German chamber music. During his time in the UK and Europe, Gerald performed with his British ensemble, Rinnovatori, at two of the world's most prestigious early music festivals, Musica Antiqua Bruges (MAfestival Brugge) and Festival Oudemuziek Utrecht.
A keen interest in keyboard performance practice led Gerald to switch his performance major from the piano to the harpsichord while reading for his undergraduate music degree at the University of Birmingham, UK. He owes much of his formative years there to his teacher, Christine Whiffen, as well as studying 17th- and 18th-century improvisation under Paula Chateauneuf. Gerald's musical diversity is reflected in his choice of double majors in harpsichord performance and a musicology dissertation on the influences in Charles-Valentin Alkan's music – the latter under the supervision of Prof. Kenneth Hamilton. He also collaborated with the university's drama department in a period revival production of Wilkie Collins' play, The Red Vial. Under the direction of Dr. Caroline Radcliffe (herself a former baroque oboist with the British period orchestra, King's Consort), he improvised and provided music to the play on an 1851 Erard fortepiano in accordance with Victorian stage performance practice. After graduating top of his cohort at Birmingham, he went on to complete his master's with distinction at the Royal Academy of Music, UK, where he studied the harpsichord and fortepiano under Carole Cerasi, and the clavichord and basso continuo with Terence Charlston. He was twice awarded the academic prize at Birmingham and the early music prizes both at Birmingham and at the Academy.
Much of Gerald’s early musical training started on the piano under Low Shao Ying in Singapore and David Quigley in the UK. Under the tutelage of the former, he went on to attain a Licentiate of the Royal Schools of Music with distinction in piano performance. Gerald was also selected by the Ministry of Education in Singapore to attend the Pan Pacific Music Camps (Advanced Piano School) in Sydney, studying principally with Marc Durand.
Outside the field of music, Gerald occasionally dabbles into photography. One of his works was published in the 2012 National Day edition of National Library Board's journal, BiblioAsia.
