Dr. Elisa H. Ignatius is an infectious diseases and clinical pharmacology specialist at the Johns Hopkins University School of Medicine.

Research Summary
Dr. Ignatius’s research focuses on clinical pharmacology of anti-mycobacterial regimens, for both tuberculosis and nontuberculous mycobacteria infections. This includes clinical trials of drug-drug interactions, pharmacokinetics-pharmacodynamics, and pharmacokinetics-toxicodynamics. By applying clinical trials framework and experience from the study of tuberculosis to the field of nontuberculous mycobacteria, Dr. Ignatius aims to improve the treatment of both diseases with both novel and standard of care regimens.
