Christina L. Lancioni M.D.

    • Associate Professor of Pediatrics, Division of Infectious Diseases School of Medicine
    • M.D./Ph.D. Program Committee School of Medicine

Dr. Lancioni’s research focuses on understanding how the human immune system responds to infection with mycobacterium tuberculosis. She is actively engaged in both laboratory and clinical research projects that aim to understand why young children develop severe forms of tuberculosis disease, and how to better diagnosis tuberculosis in children.
