Prof Cheng also spearheaded the project ‘A Minimally-Invasive Surgery (MIS) research centre based on a robotic surgery unit da Vinci system) and an image-guided intervention unit’ funded from Ministry of Health, Singapore in 2003. Prof Cheng was the Principal Investigator to develop the Urological Oncology Unit at the Department of Urology for Basic and Clinical Research in Urinary Tract Cancer, fully funded by the then Singapore Totalisator Board.
He has over 90 publications in local and international journals on Prostate Cancers, Bladder Cancers and Stone Diseases. He has contributed to several book chapters on urology in local and international publications. He is on the editorial board of several well-known journals, namely Journal of Robotic Surgery and Oncology & Haematology News.
