He was awarded a HMDP Fellowship to pursue further training in the subspecialty of Maxillofacial Prosthetics at the Memorial Sloan-Kettering Cancer Center in New York in 2001. 

This subspecialty involves multidisciplinary management and prosthetic rehabilitation of head and neck cancers patients who suffer from the sequelae of the oncologic treatments. In collaboration with the Speech Therapy Department SGH, he established the Prosthetic, Speech and Swallowing Rehabilitation Clinic (PSSR) at NDCS in 2003. The PSSR Clinic provides a multidisciplinary management for patients with speech and swallowing disorders following radiation therapy, surgical resection or cerebro-vascular disorders requiring prosthetic intervention.

Apart from maxillofacial prosthetics, his clinical practice involves comprehensive management of patients requiring fixed, removable and implant prosthodontic rehabilitation. 

He has been appointed as Associate Director of the NUS Residency Training Program for Prosthodontics since 2008. As an Associate Director, he was involved in the clinical training of the prosthodontics residents and their research thesis projects. As National Dental Centre Singapore's Deputy Director for Clinical, he oversees the clinical service, its governance and productivity. He has put in a framework to improve productivity through close monitoring of chair utilization, reducing no-show rates and engaging part-timers to backfill when clinicians are away doing research, administration or teaching. 

He contributes to the dental profession through his involvement in professional bodies and providing quality continuing education locally and internationally. Presently, he serves as a member of the Dental Specialists Accreditation Board for Prosthodontics and as a member on the Singapore Dental Council Complaints Panel and Discipline Committee.
