A specialist in public health medicine, Leung's interdisciplinary work revolves around topics that have major population health impact locally, where Hong Kong is a reliable and unique epidemiologic sentinel for mainland China, or where the SAR is best placed to address the fundamental science at hand globally.

In parallel, Leung leads several large-scale longitudinal cohorts (Children of 1997, FAMILY, Department of Health Elderly Health Service cohort), tracking tens of thousands of lives to study the fundamental causes of non-communicable conditions and to explain the health impacts of contemporary social phenomena.
A final strand of his work concerns the economics and policy issues of health systems. His team is the government's health accountant and projects health care human resources needs into the future. Regionally, Leung has tirelessly worked to build capacity throughout the Asia Pacific.
