ORCID: 0000-0003-3788-8114

Researcher ID: A-3145-2012


Dr. Wong majored in Geography and Resources Management in her undergraduate days, and conducted research in the spatial epidemiology of methadone maintenance treatment utilization for her M.Phil study in the Chinese University of Hong Kong (CUHK). Her geographic information system (GIS) skills were further trained when she worked as a GIS assistant consultant in an environmental impact assessment company, and in an IT company which resells Google geo-products. She established her research skills and knowledge of infectious diseases and public health when she worked as a research assistant in Stanley Ho Centre for Emerging Infectious Diseases, CUHK, for around 4 years. She was also a part-time PhD student in School of Public Health, CUHK. Her doctoral study aimed at estimating HIV population viral load and simulating the impact of test-and-treat intervention on the HIV epidemic growth in Hong Kong through epidemic modelling. She later joined a joint China-US postdoc programme, working in South China-UNC STD Research Training Center in Guangzhou, and University of North Carolina at Chapel Hill in US. Her postdoctoral studies focused on the HIV linkage and retention in care, and syphilis epidemiology with the use of epidemic modelling and spatiotemporal analyses in South China.

Research Interests

  • Epidemiology of infectious diseases, including HIV, Hepatitis B, Hepatitis C, syphilis, Influenza, TB, dengue and COVID-19

  • Application of spatial, temporal, social networking, epidemic modelling and molecular techniques to study epidemiology

  • Immune recovery of HIV patients following antiretroviral therapy
