He is also an Associate Professor with the Department of Surgery, Yong Loo Lin School of Medicine. His vision is to help thousands of patients in Singapore and around the globe through cutting edge, less traumatic heart surgery. He promotes and offers a wide range of traditional and less invasive, small-incision and keyhole access procedures for bypass and heart valve surgery. He has a wide spectrum of expertise in Less Invasive and Hybrid Heart Surgery, Heart Failure Surgery and Off-pump procedures.  He has introduced numerous new technologies of his field in the region, as well as launched new types of less invasive surgery, now featuring on professional forums and the Internet across the globe. He is invited around the world to train doctors and nurses in Minimally Invasive Heart Surgery as well as to hold workshops. He has established a Unique Centre of Excellence in Minimally Invasive Heart Surgery with the support from NUHCS/NUHS Leadership and industries in the field.

 

He has trained in some of the world’s leading institutions (Rochester, NY/Texas heart, Houston/Hannover Germany, Stanford, CA, USA). He is decorated with numerous international awards and carries various offices and commitments internationally.
