As a PhD student at the University of Hong Kong, Zhenyu Wang research focuses on mathematical modelling and cost-effectiveness analysis. This interdisciplinary field combines epidemiology, health economics, and computational modelling to better understand the progression and impacts of various health conditions. Through his doctoral studies, he is exploring advanced techniques to model the natural history of diseases - that is, the typical course and development of a disease over time without intervention. By capturing the underlying biological and social drivers of disease progression, these models can provide valuable insights to inform public health decision-making.
