Research Interests

Dr. Johnson's research interests have focused on phase I, II, and III IND and non-IND clinical trials of new drugs, immunotherapeutic agents and vaccines for the prevention and treatment of tuberculosis. Other areas of interest include HIV and TB interactions, immunopathogenesis of M. avium complex disease and tuberculosis, TB diagnostics, tuberculosis, HIV vaccines, surrogate markers of response to TB treatment, pulmonary infections in immunocompromised persons, and research capacity strengthening in developing countries. Dr. Johnson is the component leader for clinical trials for the NIH-sponsored Tuberculosis Research Unit at CWRU and the Principal Investigator for tuberculosis clinical trials for Site 30 Kampala, Uganda of the CDC-sponsored Tuberculosis Trials Consortium (TBTC) network.
