Dr Nancy Leung obtained her BSc (Biochemistry) in 2009, MPhil (Microbiology) in 2012 and PhD (Public Health) in 2015. She is currently a post-doctoral researcher in infectious disease epidemiology, with major interest in immunity to influenza and other respiratory virus infections. She has been involved in the design and analysis of epidemiological studies on influenza burden, transmission, vaccine immunogenicity and population immunity in Hong Kong and mainland China. Her long-term research goal is to study the mechanisms of immunology in humans by combining the research fields of epidemiology and basic immunology. To this end, she has completed an MPhil focusing on the molecular mechanism of antibody-dependent enhancement of SARS-CoV infection to evaluate the safety of a SARS vaccine candidate; and during her PhD a series of field studies on the aerosol transmission of influenza virus. She also has an interest in field epidemiology, and has experience in designing and adopting electronic systems for data capture, specimen tracking, and workflow monitoring.
