  • Undergraduate Teaching

    The Division assists with undergraduate epidemiology and biostatistics teaching in the MBChB curriculum (including during Semesters 3-5, and as part of the 4th year Public Health teaching programme) and as part of research methods teaching for allied health sciences students.

  • Postgraduate Teaching

    The Division provides epidemiology and biostatistics teaching at both introductory and advanced levels. Most of the Division's teaching is through the Master of Public Health (MPH) programme, where the Division convenes the Epidemiology and Biostatistics track.

    Courses taught by the Division include:

    • Introduction to Epidemiology
    • Advanced Epidemiology
    • Clinical Epidemiology
    • Seminars in Epidemiology
    • Infectious Diseases Epidemiology (taught in conjunction with the Division of Public Health Medicine)
    • Non-Communicable Diseases Epidemiology (taught in conjunction with the Division of Public Health Medicine)
    • Evidence-Based Health Care (taught in conjunction with the Department of Medicine)
    • Biostatistics I (Introduction to Biostatistics)
    • Biostatistics II (Linear & Logistic Regression Modelling)
    • Biostatistics III (Survival analyses and advanced topics) (taught in conjunction with the Department of Statistical Sciences)
       

    Additional teaching takes place on a range of short-courses and special seminars throughout the Faculty. This additional teaching typically focuses on either general research methods (study design, measurement, causal inference, etc) and/or specific advanced topics. Recent topics for short-courses and seminars include:

    • mathematical modelling of infectious diseases
    • structural equation modelling
    • missing data and imputation
    • modelling for causal inference
       

    In addition, the Division offers PhDs in Epidemiology and Biostatistics. While the PhD programme is by dissertation-only, most of our PhD students enter through the MPH, and/or participate in short-courses and seminars programme.

  • Research

    Research interests and activities in the Division include:

    • Methods for modelling longitudinal data
    • Infectious diseases epidemiology, including HIV, tuberculosis and sexually transmitted infections
    • Maternal and child health
    • Cardiovascular diseases
    • Women's reproductive health, including contraception and termination of pregnancy
       

    Researchers in the Division collaborate with investigators in other parts of the School of Public Health and Family Medicine (including CIDER and WHRU) and the Faculty (including the Departments of Paediatrics and Child Health, Clinical and Laboratory Sciences, Psychiatry and Mental Health, Medicine).

Current interests are in supervised learning as related to cytokine and other biomarker assay profiles, particularly in TB disease progression and Bayesian mixture models for longitudinal HIV viral load data. Constant distractions are statistical graphics, ‘composite’ statistical methods, algorithmic statistical methods (aka machine learning) and R programming. The Biostats Lab works 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). We also run a regular statistical methods seminar series on the Health Sciences Faculty – announced on web and via twitter (@EpiBiostats_UCT).
