On the TB front, Gaseitsiwe has ongoing work exploring latent TB infection in Botswana and predictors for development of active TB in patients on antiretroviral therapy. He has collaborations with various academic institutions allowing him to supervise and co-supervise graduate students at University of Botswana (UB), Botswana International University of Science and Technology (BIUST), and University of Kwazulu-Natal (UKZN). Most of these students do the research work at the BHP laboratory under his direct supervision.
