Steve was Professor of Infectious Diseases and Tropical Medicine at LSHTM and an active member of the LSHTM TB Centre . He worked closely with the Desmond Tutu HIV Centre at the University of Cape Town (UCT), where he was based from 2005- 2012.  Steve worked tirelessly to improve the diagnosis and treatment of tuberculosis among people living with HIV/AIDS. He authored over 250 publications and received many awards.  

​This year’s memorial lecture is titled The Know-Do Gap in Tuberculosis Care and will be delivered by Professor Madhukar Pai.

Poor quality care is killing people with TB and keeping the epidemic alive. Standardised (simulated) patient studies in 8 countries show widespread lack of quality, and a massive gap between what providers know and how they practise. Even where technical quality is good, health systems are failing on client-centeredness. The TB field must think beyond coverage and demand high quality care for all TB patients in all countries. If we are serious about ending TB, we must put quality on the agenda, in addition to expanding coverage of critical interventions.
