We are a collection of biostatisticians, research fellows, and students working on various topics in the Division of Epidemiology & Biostatistics, School of Public Health & Family Medicine at the University of Cape Town. Current research themes are looking at biomarker monitoring in chronic disease (eg viral load monitoring during pregnancy and postpartum) and a number of investigations into longitudinal modelling of exposures related to lung health in Africa.

(almost) all of us

We work with the Cape-R Users Group to promote R programming around the Cape and wider afield, please join if you are local to Cape Town (twitter @CapeRUser).

Hosted by the Division of Epidemiology & Biostatistics, School of Public Health & Family Medicine, University of Cape Town.

This project is part of the European and Developing Countries Clinical Trials Partnership (EDCTP2) programme supported by the European Union (TMA2017SF-1959)


Collaborative Biostatistics Training Workshop

We will be running our first workshop focused on early career biostatisticians in June 2019 in Tanzania. Dates are 13-14 June at the White Sands Hotel, Jangwani Beach, Dar Es Salaam. We are currently taking applications. Topics: The many roles of the collaborating biostatistician Collaboration with clinical researchers (theory & practice) Development of collaboration skills …
