Alison Grant’s research interest is evidence-based care for HIV-positive people in resource-limited settings, particularly the development and evaluation of interventions to reduce morbidity and mortality due to tuberculosis.


Since 1997, Alison’s research has focused on the intersection between HIV and tuberculosis in South Africa.  She took up leadership of the new TB programme at the Africa Centre for Population Health in 2014.

Recent major projects:

  1. TB Fast Track, a cluster-randomised trial in 24 primary care clinics in South Africa aiming to reduce early mortality on antiretroviral therapy by improving detection and early treatment of active tuberculosis, funded by DfID/MRC/Wellcome Trust Global Health Trials.
  1. XTEND: a cluster-randomised trial evaluating South African national roll-out of the new tuberculosis diagnostic test Xpert MTB/RIF, primarily its impact on mortality among people being investigated for tuberculosis, funded by the Bill and Melinda Gates Foundation.
  1. XPHACTOR: an interventional cohort study investigating how to prioritise TB investigation among HIV clinic attendees, funded by the Bill and Melinda Gates Foundation.
  1. Lesedi Kamoso: a study nested within TB Fast Track, XTEND and XPHACTOR, investigating causes of death and comparing minimally invasive autopsy with verbal autopsy, funded by the Bill and Melinda Gates Foundation.
  1. RR linkage study: a retrospective cohort study investigating linkage to care among people found to have rifampicin resistance on testing with Xpert MTB/RIF in South Africa, funded by the Bill and Melinda Gates Foundation.
  1. Thibela TB: a cluster-randomised trial of mass screening and isoniazid preventive therapy (IPT) for tuberculosis control involving 80,000 gold miners, funded primarily by the Bill and Melinda Gates Foundation.
