About

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.

Clustering of longitudinal viral loads in the Western Cape

The abstract and a few summary figures of the MPH mini-dissertation submitted by Eke Arua for his degree. Abstract Introduction: Data from routine viral load monitoring is important for assessing the programmatic effectiveness of antiretroviral treatment (ART) in South Africa, but this is usually analysed in a cross-sectional manner and there are few analyses of …

Maia Lesosky, PhD (0000-0002-2026-958X)

Biostatistician & Associate Professor
Head, Division of Epidemiology & Biostatistics, School of Public Health & Family Medicine,
University of Cape Town, South Africa

Academy of Medical Sciences Newton Advanced Fellow, Liverpool School of Tropical Medicine
EDCTP2 Senior Fellow, BiostatsLAB-Africa
Contributing investigator, Wellcome Centre for Infectious Diseases Research in Africa (CIDRI-Africa)

Maia is an applied biostatistician with more than a decade of experience in heath sciences research, the last six of which have been spent working with clinical researchers in Africa. Maia currently works with clinicians and epidemiologists in TB, HIV and respiratory disease related research as well as having a program of NIH, EDCTP and Academy of Medical Sciences funded research for biostatistical methods work. She teaches biostatistics anywhere she can, but mainly as part of the University of Cape Town Masters of Public Health programme & PATS MECOR.
