Dr. Chung joined the School of Public Health and Primary Care (SPHPC) of the Chinese University of Hong Kong (CUHK) in 2011. Using the lens of biomedical ethics and justice, his research aims to empirically inquire into the social determinants of health inequalities (including poverty and health, migrants’ health, rare diseases patients’ health), as well as aging‐related issues on multimorbidity and long‐term/end‐of‐life care, and to utilize such evidence to inform health services and policy, domestically and beyond.

Dr. Chung is the founding Associate Director of the CUHK Institute of Health Equity established in January 2020 under the co‐directorship of Sir Prof Michael Marmot, Prof Eng‐Kiong Yeoh, and Prof Jean Woo. He is also a founding member of the Centre for Health Systems and Policy Research, a founding member of the Research Centre for Migration and Mobility, an executive member of the Centre for Health Systems and Policy Research, Centre for Quality of Life, and an Assistant Professor (by courtesy) at the CHUK Institute of Ageing.

On an international level, Dr. Chung is the Vice Chair of the Public Health Global Challenge Steering Group of the Worldwide Universities Network (WUN), spearheading the direction of research and collaboration in public health for 23 international research universities in the world. In September 2018, Dr. Chung was elected the Inaugural National Academy of Medicine (NAM) International Health Policy Fellow by the prestigious NAM in the US, studying social determinants of healthy longevity. Moreover, he has served in various official consultation committees of the Hong Kong Government, including the Domestic Health Accounts and Thematic Household Survey of the Food and Health Bureau, and has been involved in two Government commissioned projects on
elderly/end‐of‐life care and healthcare resource allocation exercise. He was a principal investigator of a Hospital Authority consultancy study on medical assistance programs and a commissioned study on rare diseases in Hong Kong. Dr. Chung’s research has also been featured as the cover story of CUHK Newsletter (Nov Issue #507). Dr. Chung has had numerous publications including 70+ academic articles in leading high‐impact peer‐reviewed journals, book chapters and consultation reports.

​Furthermore, he has been actively involved with University‐, College‐, Faculty‐ and School‐level services as well as external social services with considerable public impact – he is the Vice President of Hong Kong Life and Death Studies Association (香港生死學協會), a social enterprise integrating professional knowledge and ideas from a wide range of young professionals in innovating life and death education, advance care planning, longterm care and after‐death arrangements in Hong Kong; and he is a co‐host of the only “Life and Death
Education” Radio Program in Hong Kong. Apart from his academic life, he is also an award‐winning and celebrated recording artist/producer.

Dr. Chung obtained the Bachelor degree in Public Health from Johns Hopkins University and Master of Health Science from Johns Hopkins Bloomberg School of Public Health in the US in 2005. He further received his Doctor of Philosophy (PhD) degree from the School of Public Health of the University of Hong Kong in 2011, with his study on the impact of socioeconomic development on population health, from which he also won the Presidential Award for Best Oral Presentation from the Hong Kong College of Community Medicine.
