Shaun is a prizewinner at more than ten international competitions, including nine first prizes. He emerged victorious at the 3rd International Piano Competition Istanbul Orchestra’ Sion and is a five-time prizewinner in international Chopin competitions held in Hungary, France, China, South Korea and Australia.

Back home, Shaun is featured in many local publications such as The Straits Times, Lianhe Zaobao, The Epoch Times, TimeOut and Pioneer magazines, among others. His album “Chopin the Complete Preludes” was awarded the top three best classical albums of 2018 by the Straits Times. He adjudicated at the Nanyang International Piano Competition, Lucien Wang Piano Competition and SMTA’s Performers' Festival. He is an Adjunct Lecturer at the Nanyang Academy of Fine Arts. Shaun gave solo recitals at both the Esplanade
Concert Hall in 2014, and at the Victoria Concert Hall in 2022, the latter as part of the 28th Singapore International Piano Festival organised by the SSO. He was also invited by Resound Collective on several occasions.

Shaun is an increasingly sought-after teacher, with many of his students winning prizes in international competitions themselves. He is frequently invited to conduct masterclasses and lectures, often at established institutions such as the Steinway STEPS program, Keimyung University (Daegu, South Korea), Bela Bartok University (Miskolc, Hungary) and the International Summer Academy Mozarteum (Salzburg, Austria). He holds the title of Adjunct Lecturer at the Nanyang Academy of Fine Arts Singapore.

As an avid composer, Shaun often performs his own works during recitals. He was commissioned by the Singapore Armed Forces to compose the Signal Formation Song during his two-year military service. His 4-hands work “Fiestravaganza” has nearly 6 million cumulative views on YouTube. It has won numerous prizes at duo competitions and has sold hundreds of copies online.

In 2022, Shaun formed the Camerata Fiestravaganza, a new chamber orchestra which brings together over 40 personally-selected talented musicians from diverse cultures and ethnicities, the majority of whom are current students from the three major Universities of music in Berlin – Universität der Künste, Hochschule für Musik Hanns Eisler and Barenboim-Said Akademie.

The following year, he founded the Fiestravaganza International Music Academy (FIMA). The first major piano summer academy in the German capital, FIMA offers particularly young talents a variety of opportunities otherwise hard to obtain in one’s early career. Participants gain recognition through numerous performances, while working with renowned instructors and guest speakers via the masterclasses/seminars offered. They will also get the exclusive chance to work on Bechstein’s extensive Vintage Keyboard Instrument collection. As the highlight, selected participants will get to perform a movement of a piano concerto with the Camerata Fiestravaganza, hosted in the great halls of the academy’s cooperation partner – the University of the Arts Berlin.

Shaun is the first and only external piano candidate in many years to be successfully admitted into the prestigious “Konzertexamen” Postgraduate Program at the Berlin University of the Arts, Germany, where he will further his studies from 2020 under the tutelage of professor Björn Lehmann.
