Wenwen Liu is a master’s student in epidemiology and biostatistics who plans to begin a PhD programme. Her research interests focus on infectious disease transmission, vaccination strategies, and public health policy. Wenwen's current work examines HPV transmission among men who have sex with men (MSM) using a dynamic network framework combined with a health economic evaluation. This work considers behavioural heterogeneity, vaccine hesitancy, and intervention design in high-risk populations. Her background and training include statistical modelling, epidemiological methods, and computational simulation. The research aims to support the development of evidence-based and cost-effective vaccination strategies with relevance for public health decision-making.
