Dr. Gary Chung is a social epidemiologist who studies public health issues and related social determinants of health through an equity lens. With a nutritionist background, Dr. Chung obtained his PhD in Public Health at the JC School of Public Health and Primary Care of the Chinese University of Hong Kong, focusing on the socioeconomic patterning of obesity and cardiometabolic conditions. His research interests go beyond nutrition-related issues but also cover mental health, healthcare access, health and social impact of the COVID-19 pandemic, population health monitoring, and related health equity issues across the socioeconomic ladder, gender, and ethnic minority groups. Before returning to the School as a Research Assistant Professor, Dr. Chung completed his postdoctoral training at the CUHK Institute of Health Equity as the awardee of the RGC Postdoctoral Fellowship Scheme 2021/22.
