William Rudgard is a post-doctoral researcher in the Department of Social Policy and Intervention at the University of Oxford. His work focuses on identifying factors that may support and empower adolescents living with HIV in South Africa to participate fully in this critical period of life. He is particularly interested in the role of social protection and social support for achieving this. William completed his PhD in 2019 through the Department of Non-Communicable Disease Epidemiology at the London School of Hygiene and Tropical Medicine. Spanning the fields of Epidemiology, Health Economics, and Social Policy, his doctoral work focused on the potential of cash transfers to prevent financial hardship from severe illness, with a particular focus on the infectious disease tuberculosis. Funded by the MRC UK, the PhD used ecological, cross-sectional, and longitudinal data, and explored the use of quasi-experimental methods for impact evaluation.
