Willings Botha

Adjunct Lecturer

Willings Botha is a Research Fellow in Health Economics at the National Perinatal Epidemiology and Statistics Unit (NPESU), Centre for Big Data Research in Health and School of Women’s and Children’s Health. He previously worked as a Research Assistant in Health Economics at the University of Glasgow, Scotland, UK where he also completed his PhD in Health Economics focusing on the development of a broader economic evaluative space for public health interventions. He developed an integrated approach that combines the traditional cost-utility analysis for health outcomes with the stated preference discrete choice experiment for non-health related outcomes on a single monetary scale using the net monetary benefit framework.

His research interests lie in the area of stated preference discrete choice experiments. He is currently working on the economics of fertility treatment to value outcomes that go beyond health.

He welcomes collaboration in health economics research, especially that which aims to value both health and non-health related outcomes of an intervention.
