Prof. Dr. Gerhard Walzl is a clinician scientist, trained in internal medicine and pulmonology and lead the Stellenbosch University Immunology Research Group in Cape Town, South Africa. The research of the team focuses on the immunology of Mycobacterium tuberculosis (MTB) infection and in particular host biomarkers, including diagnostic markers, markers of TB treatment response and markers of protective immunity against MTB. His team performs both clinical and laboratory research. We conduct clinical studies to recruit participants with well-characterized MTB infection and disease phenotypes in a high TB-incidence setting to search for host biomarkers and the ultimate aim is to develop field-friendly tests to combat TB. His research spans the divide between clinical and basic sciences in a high TB prevalence area.
