Mr Wim Delva

Assistant Professor


Wim Delva is a medical doctor by training, with a PhD in Medical Sciences (focused on HIV epidemiology). His work involved the development of individual-based simulation models and the application of statistical and mathematical modelling techniques to describe and analyse the behavioural and biological processes underlying HIV epidemics. Wim recently became the acting director for DiSeCT, the new School for Data Science and Computational Thinking at Stellenbosch University.
