Tawanda Gumbo, M.D., was born in Zimbabwe, and attended the University of Zimbabwe Medical School. From 1993 to 1996 he was an intern and resident in Internal Medicine/International Health Tract at Case Western Reserve University at MetroHealth Medical Center in Cleveland, Ohio, and from 1996-1999 he was a fellow in Infectious Diseases at the Cleveland Clinic Foundation in Cleveland, Ohio.

In 2001 he joined the Albany Medical College and the Ordway Research Institute in Albany, New York, where he worked on establishing the mouse model of disseminated Candida glabrata and the hollow fiber model of tuberculosis in 2002. He was the inaugural Director of Transplant Infectious Diseases for the newly established transplant surgery program, and the Infectious Diseases member of Center for Donation and Transplant (CDT), a UNOS organ procurement organization for New York, Vermont, and Western Massachusetts.

In 2006 he moved to UT Southwestern Medical Center. The Gumbo Laboratory has elucidated the role of efflux pumps in survival of Mycobacterium tuberculosis and examined molecules that could exploit these to enhance antituberculosis therapy. Work has also included integrating pharmacogenomics into clinical trial simulations for antituberculosis drugs with multimodal systemic elimination, establishment of a mathematical model for the relationship between antimicrobial drug exposure and resistance emergence, the establishment of new susceptibility breakpoints of first-line antituberculosis drugs, and recently a series of hollow fiber model of tuberculosis and computer-aided clinical trial simulations as well as clinical data that have questioned the role of adherence in therapy failure and proposed the pharmacokinetic variability hypothesis for therapy failure and acquired drug resistance. These findings were then confirmed in a series of clinical studies conducted jointly with research partners at the University of Cape Town. 

In 2007 he received the NIH Director’s New Innovator Award to focus on efflux pump inhibition to accelerate therapy and reduce duration of antituberculosis therapy. In 2009 he was a Mellon Visiting Scholar at the University of Cape Town in South Africa. In 2013 the hollow fiber model of tuberculosis was presented before the FDA, and in 2014 presented to the European Medicines Agency for qualification as a drug development tool by CPTR. 

He is a contributor for two chapters in the 12th edition of the pre-eminent pharmacology text "Goodman and Gilman’s The Pharmacological Basis of Therapeutics" namely, "Principles of Chemotherapy of Infectious Diseases" and "Chemotherapy of Tuberculosis, Mycobacterium avium Complex, Leprosy." Dr. Gumbo has also published a poetry book, "Songs for flame lily" (2005), that is arranged based on courtship stages of traditional Bantu society.

He joined UT Southwestern's Office of Global Health in 2011.
