Jonathan attended the Singapore Management University’s School of Law and graduated in 2013 with a Bachelor of Laws (Summa cum Laude) and Bachelor of Business Management (Finance) (Summa cum Laude). He is fluent in English, Mandarin, Cantonese, and basic Bahasa Melayu.

Upon graduation, Jonathan served as Deputy Public Prosecutor for a short period of time before being posted to the Supreme Court of Singapore as a Justices Law Clerk for two years where he assisted the Singapore High Court and Court of Appeal on a variety of matters involving different fields of law. Two of the judgments Jonathan assisted on have since become landmark decisions on administrative law and litigation funding.

After his stint in the Judiciary, Jonathan was called to the Singapore Bar in 2016. Since then, he has worked with senior local and international practitioners in private practice, including practitioners from the United States of America, the United Kingdom, the People’s Republic of China, Hong Kong, Malaysia, Japan, and the British Virgin Islands. His practice area is mainly in high-value commercial litigation, arbitration, and mediation, specifically in the fields of banking, real estate, oil and gas, financial technology, and private equity. Some of the clients Jonathan has represented include Unipec Singapore Pte Ltd, Grabtaxi Holdings Pte Ltd, MS First Capital Insurance Pte Ltd, and Holdings Ltd.

Most of Jonathan’s cases involve investigations and uncovering of fraudulent conduct.

Jonathan is also an accredited mediator with the Singapore Mediation Centre and part of the FIDReC-SMC Co-Mediation Pilot Scheme. Since being empanelled, Jonathan has mediated several cases involving credit card disputes, motor insurance, and accident and health insurance. He has been commended for his ability to manage expectations and emptions well and received positive feedback for his “good control of the proceedings”, ability to build “good rapport with the parties”, and “helping explore and develop options” for the parties to amicably resolve their dispute.

Outside of private practice, Jonathan has served as an adjunct faculty at the Singapore Management University’s School of Law and contributed to several leading textbooks and journal publications, such as the Singapore Academy of Law Journal and Derivatives & Financial Instruments.

A firm believer that being part of a community also means giving back to it, Jonathan is actively involved with ReadAble Ltd, a non-profit organisation established to serve children and families from a low-income estate in the area of literacy and numeracy.
