David Dowdy is an associate professor in epidemiology at the Johns Hopkins University School of Medicine and is an expert in infectious disease epidemiology. He also practices internal medicine in East Baltimore.  He holds a joint appointment in international health at the Johns Hopkins Bloomberg School of Public Health. He is the inaugural holder of the B. Frank and Kathleen Polk Professorship.

Dr. Dowdy’s research focuses on the epidemiology of tuberculosis, the world’s leading infectious cause of death worldwide after COVID-19, with over one million deaths worldwide each year. He is interested in how interventions are implemented to better detect, diagnose, treat, and prevent TB. To answer these questions, he combines skills in epidemiology, implementation science, health economics, and disease modeling. His work has been used to inform policy from the local to the global level, including Baltimore, the Centers for Disease Control and Prevention, National TB Programs (Uganda, South Africa, Bangladesh), and the World Health Organization.

More recently, Dowdy has been involved in the COVID-19 response, taking an active role in communicating scientific findings to the public. He has been featured in The New York Times, The Wall Street Journal, CNN, NBC News, National Public Radio, and other leading media outlets.

Dr. Dowdy received his BS from Duke University and earned his ScM and MD/PhD from Johns Hopkins. He performed his residency at the University of California, San Francisco School of Medicine.
