Associate Professor Christopher Cao was the first Australian surgeon to complete a Fellowship in robotic thoracic surgery, when he operated with Dr. Bernard Park, the first surgeon to perform robotic thoracic surgery in North America, and Dr. Valerie Rusch, the President of the American College of Surgeons. His specialized robotic training was completed in Memorial Sloan Kettering Cancer Center, New York City, the largest and oldest private cancer hospital in the world. Since his clinical practice began in Sydney, Dr. Cao has performed one of the highest numbers of robotic thoracic operations in Australasia.
