Francis Ka Leung Chan

Francis Ka Leung Chan  is a Hong Kong gastroenterologist. He is the former Dean of the Faculty of Medicine, Chinese University of Hong Kong (CUHK) and the Choh-Ming Li Professor of Medicine and Therapeutics. Previously, he was the Associate Dean (Clinical) of CUHK Faculty of Medicine and the director of the Institute of Digestive Disease at CUHK.

Early life and education
Chan was raised at Ngau Tau Kok, Hong Kong. He lived at Kwun Tong Garden Estate, a public housing estate, with his parents and younger brother until Form 4 (roughly equivalent to Year 10 in the English education system. Although his father graduated from a university in China, his degree did not benefit him in Hong Kong and so became a taxi driver. He completed his secondary education at St. Francis Xavier's College.

In 1983, Chan enrolled in the Faculty of Medicine of the Chinese University of Hong Kong (CUHK), which had been established only two years ago. His teachers were surprised as most students who aspired to be physicians at the time would select the older and more famous Faculty of Medicine of the University of Hong Kong. Chan cited his desire to explore new frontiers, instead of following others' path, as the reason behind his decision. He was at Chung Chi College during his undergraduate years. He graduated with an MBChB degree in 1988 as the top student in his class and with the gold medal in Surgery. Drawn by Joseph Sung's enthusiasm in teaching aspiring physicians, he joined Department of Gastroenterology at CUHK Faculty of Medicine.

Chan obtained his Doctor of Medicine (MD), which in Hong Kong is a research degree, from CUHK in 1998.

Career
In 1993, Chan received a Croucher Fellowship and went to the University of Calgary in Canada to conduct research in liver transplantation in mice.

Chan joined Faculty of Medicine of the Chinese University of Hong Kong (CUHK) as a lecturer in 1997, and became a professor at the Department of Medicine and Therapeutics in 2005.

In 2010, after Joseph Sung assumed the role of Vice-Chancellor and President of CUHK, Chan took up one of Sung's previous role, the Director of the Institute of Digestive Disease. At the same time, Chan was appointed the Associate Dean (Clinical) of CUHK Faculty of Medicine.

Chan left his position of Associate Dean (Clinical) on 1 January 2013 to become the interim Dean of CUHK Faculty of Medicine. He officially took up the Deanship on 1 February 2014.

Chan's tenure as Dean ended on 31 January 2024,  when Philip Wai Yan Chiu, the Associate Dean (External Affairs) of CUHK Faculty of Medicine and a professor at the Department of Surgery, will succeed him.

Concurrently, Chan is a member of the Hospital Governing Committee of Prince of Wales Hospital, a member of the Hospital Authority Board since 1 April 2013, and practices at CUHK Medical Centre, a private, non-profit hospital and teaching partner of CUHK.

As Dean of the CUHK Faculty of Medicine, Chan has been an ex-officio member of the Medical and Health Services sector of the Election Committee of Hong Kong since 2021 after the electoral changes enacted that year.

Chan co-founded biotechnology company GenieBiome in 2019. The company aims to make use of the human microbiome as a disease treatment.

Research
Chan's research began with studying the treatment of gastric bleeding and peptic ulcers caused by Nonsteroidal anti-inflammatory drugs (NSAIDs). In 1997, he reported that eliminating Helicobacter pylori before administering NSAIDs reduced the incidence of NSAID-induced peptic ulcers. At the time, the research community focused on the treatment for H. pylori to prevent gastric bleeding. His research prompted a debate on the effect and benefit of H. pylori elimination before NSAID therapy.

In recent years, Chan has focused on studying human microbiome and its effect on health.

Personal life and family
Chan's younger brother is Samuel Ka-yan Chan, chairman of the Competition Commission of Hong Kong.

Chan married his wife, also a physician, in 1993.
