Overview

Dr. Nancy Leung is currently a Takemi Fellow in International Health at Harvard Chan School of Public Health, and Assistant Professor at School of Public Health, The University of Hong Kong. Her research focuses on infectious disease epidemiology, with a long-term research goal of conducting impactful research on susceptibility to infectious diseases in particular respiratory virus infections. In recent years, Dr. Leung is designing large-scale longitudinal cohorts, vaccine trials and field studies on individual and population immunity, vaccine immunogenicity, disease burden and transmission of influenza viruses, coronaviruses and other respiratory viruses. Dr. Leung is a co-Chair for the World Health Organization (WHO) technical working group on COVID-19 airborne risk assessment, and a member of the WHO advisory group on the routes of transmission of respiratory pathogens. Dr. Leung has been featured as one of the “Five science stars making their mark in China” by Nature Index.

Dr. Leung has completed comprehensive research training in the epidemiology (PhD) and virology/immunology (MPhil) of human respiratory virus infections. Her postdoctoral research focuses on the epidemiology of human respiratory virus infections, understanding different modes of transmission, estimating disease burden in the community, evaluating individual immune responses after influenza virus infections or repeated vaccinations, and lately focusing on immune responses after COVID-19 vaccination and infection (h-index 15, citations 2,241, including 2 Highly Cited Papers and 1 Hot Paper in Field). During PhD, she designed a series of field studies on the aerosol transmission of influenza virus, coronaviruses and other respiratory viruses. Her MPhil focused on conducting wet-lab experiments at the virus-host interface to investigate the molecular mechanism of antibody-dependent enhancement (ADE) of the SARS coronavirus. Dr. Leung has a strong interest in field epidemiology, in particular on designing and adopting electronic systems for data capture and quality control, specimen tracking and workflow monitoring to facilitate the management of large-scale community studies. She also teaches an introductory epidemiology course at the graduate level.

Dr. Leung has over 10 years of experience in both local and international interdisciplinary collaborative research, with epidemiological studies and collaborators locally in Hong Kong as well as in the US, UK and mainland China. She has received funding supports from major local and international grants including the Hong Kong Health and Medical Research Fund, Theme-based Research Scheme, the China Guangdong Natural Science Fund, the United States NIAID Centers of Excellence for Influenza Research and Surveillance/ Response (CEIRS/ CEIRR) network and the United States Centers for Disease Control and Prevention (CDC). She is a reviewer for international academic journals across different disciplines such as JAMA, Nature Microbiology, Science Translational Medicine and Environmental Science & Technology; and research funding agencies including UK Medical Research Council and Wellcome Trust.
