Wenwen Liu, a master’s student in epidemiology and biostatistics, plans to begin a PhD program. Research interests focus on infectious disease transmission, vaccination strategies, and public health policy. Current work examines HPV transmission among men who have sex with men (MSM) using a dynamic network framework combined with health economic evaluation. This work considers behavioral heterogeneity, vaccine hesitancy, and intervention design in high-risk populations. Training includes statistical modeling, 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.
