Dr. Zimvo Obasa is a postdoctoral researcher at Stellenbosch University, specializing in Molecular Biology. She holds a BSc degree in Human Life Sciences (2014), an MSc in Human Physiology (2017), and a PhD in Molecular Biology (2021). During her doctoral studies, Dr. Obasa focused on elucidating host immune responses triggered by Mycobacterium tuberculosis persisters in macrophage cultures. She also developed and validated a trackable murine model for studying Mycobacterium persister formation in Balb/c mice. Currently, her postdoctoral research is centered on evaluating the in vivo response to and efficacy of novel nanoparticle (NP) formulations as a host-directed therapy for eradicating all forms of Mycobacterium tuberculosis in C3HeB/FeJ (Kramink) mice. By utilizing the Kramnik mouse strain, Dr. Obasa aims to assess the impact of NPs on immuno-pathology and vice versa. Her work holds promise in contributing to the advancement of tuberculosis control strategies, particularly in developing more effective drug treatment regimens.
