Bio

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.

 

She was the principal investigator (PI) of a few HIV research projects, such as HIV pre-exposure prophylaxis (PrEP) implementation study, chemsex engagement cross-sectional study, and cost-effectiveness analysis for latent TB infection screening strategies in people in HIV care. She is the PI of sexually transmitted infection (STI) epidemiological studies, and HBV and HCV epidemic modelling projects in Hong Kong. She has published more than 100 articles in peer-reviewed journals, and is currently a journal editorial board member of Infectious Diseases.
