​Dr. Chew obtained his medical qualification from NUS in 2002 and started working under SingHealth Pte Ltd since 2012. He was inspired to pursue a surgical career in head and neck cancer during his housemanship. He chose cancer reconstruction due to the challenges in this field for his surgical training. He pursued further training as a Microsurgery Fellow in Chang Gung Memorial Hospital, Taiwan where he learned advanced skills and gathered much experience in handling complex cases. 

Dr. Chew helps in the formation of the SingHealth-Duke-NUS Disease Centre (SDDC) for Head and Neck as well as the Liver Transplant SDDC. Dr. Chew emphasises training and education as the cornerstone in the improvement of clinical excellence. He takes a personal interest in residency teaching and is actively pursuing research in plastic surgery, wound healing, burns, reconstructive microsurgery and basic science in transplant immunology.
