She graduated from the Chinese University of Hong Kong in 2007. She completed general surgical training and received fellowships of the College of Surgeons of Hong Kong and Royal College of Surgeons of Edinburgh in 2014. Dr. Chan’s interest is in gastric and esophageal cancers, mainly focusing in the laparoscopic and robotic approach. She did her overseas training in National Cancer Centre in Tokyo, Yonsei University in Seoul and also Amsterdam Medical Centre in Amsterdam. Her research interests include upper gastrointestinal surgical oncology and advanced diagnostic and therapeutic endoscopy especially in interventional endoscopic ultrasound.
