Dr. Jay Lim Kheng Sit

Dr Lim obtained his Bachelor of Computing from the National University of Singapore in 2005. He
completed his graduate medical degree from the University of Sydney in 2009. After housemanship
in Sydney, Australia, he returned to Singapore to serve in the local medical system. He completed
his Urology Surgical Training in 2017 and did his fellowship in robotic surgery and reconstruction
surgery at Macquarie University Hospital, Sydney, Australia, under Prof David Gillatt in 2021.
A keen innovator at heart, he was awarded the Singapore-MIT innovation fellowship in 2017 and is
actively involved in the medical device innovation scene. Dr Lim was the first medical doctor
appointed Principal Medical Investigator by Artificial Intelligence Singapore (AISG) for his
pioneering grant in Natural Language Processing.
Dr Lim’s research interest is ureteral stents, and he has been invited to speak on the topic at the
World Congress of Endourology. His clinical interest is in the field of Robotic Surgery, Endourology
and minimally invasive surgery.
