Research
Dr. Johnson’s major research focus is 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 tuberculosis and M. avium complex disease, TB diagnostics, surrogate markers of response to TB treatment, pulmonary infections in immunocompromised persons, HIV vaccines 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 TB clinical trials for Site 30 - Kampala, Uganda of the CDC-sponsored Tuberculosis Trials Consortium (TBTC) network. Dr. Johnson works closely with international collaborators in Uganda, Brazil and the Philippines.
